Note that the element
|

|
α(i,j,k) = ϱ(i,j)*ϱ(i,k)*inv(ϱ(i,j))*inv(ϱ(i,k)),
|
||||||
|
which surely belongs to ball of radius 4 in Aut(F₄) becomes trivial under the representation
|
||||||
|
Aut(F₄) → GL₄(ℤ)⋉ℤ⁴ → GL₅(ℂ).
|
||||||
|
Moreover, due to work of Potapchik and Rapinchuk [1] every real representation of Aut(Fₙ) into GLₘ(ℂ) (for m ≤ 2n-2) factors through GLₙ(ℤ)⋉ℤⁿ, so will have the same problem.
|
||||||
|
|
||||||
|
We need a different approach: Here we actually compute in Aut(𝔽₄)

> Preamble
|
|
||||||
>
|
|
||||||
> The GNU General Public License is a free, copyleft license for
|
|
||||||
> software and other kinds of works.
|
|
||||||
>
|
|
||||||
> The licenses for most software and other practical works are designed
|
|
||||||
> to take away your freedom to share and change the works. By contrast,
|
|
||||||
> the GNU General Public License is intended to guarantee your freedom to
|
|
||||||
> share and change all versions of a program--to make sure it remains free
|
|
||||||
> software for all its users. We, the Free Software Foundation, use the
|
|
||||||
> GNU General Public License for most of our software; it applies also to
|
|
||||||
> any other work released this way by its authors. You can apply it to
|
|
||||||
> your programs, too.
|
|
||||||
>
|
|
||||||
> When we speak of free software, we are referring to freedom, not
|
|
||||||
> price. Our General Public Licenses are designed to make sure that you
|
|
||||||
> have the freedom to distribute copies of free software (and charge for
|
|
||||||
> them if you wish), that you receive source code or can get it if you
|
|
||||||
> want it, that you can change the software or use pieces of it in new
|
|
||||||
> free programs, and that you know you can do these things.
|
|
||||||
>
|
|
||||||
> To protect your rights, we need to prevent others from denying you
|
|
||||||
> these rights or asking you to surrender the rights. Therefore, you have
|
|
||||||
> certain responsibilities if you distribute copies of the software, or if
|
|
||||||
> you modify it: responsibilities to respect the freedom of others.
|
|
||||||
>
|
|
||||||
> For example, if you distribute copies of such a program, whether
|
|
||||||
> gratis or for a fee, you must pass on to the recipients the same
|
|
||||||
> freedoms that you received. You must make sure that they, too, receive
|
|
||||||
> or can get the source code. And you must show them these terms so they
|
|
||||||
> know their rights.
|
|
||||||
>
|
|
||||||
> Developers that use the GNU GPL protect your rights with two steps:
|
|
||||||
> (1) assert copyright on the software, and (2) offer you this License
|
|
||||||
> giving you legal permission to copy, distribute and/or modify it.
|
|
||||||
>
|
|
||||||
> For the developers' and authors' protection, the GPL clearly explains
|
|
||||||
> that there is no warranty for this free software. For both users' and
|
|
||||||
> authors' sake, the GPL requires that modified versions be marked as
|
|
||||||
> changed, so that their problems will not be attributed erroneously to
|
|
||||||
> authors of previous versions.
|
|
||||||
>
|
|
||||||
> Some devices are designed to deny users access to install or run
|
|
||||||
> modified versions of the software inside them, although the manufacturer
|
|
||||||
> can do so. This is fundamentally incompatible with the aim of
|
|
||||||
> protecting users' freedom to change the software. The systematic
|
|
||||||
> pattern of such abuse occurs in the area of products for individuals to
|
|
||||||
> use, which is precisely where it is most unacceptable. Therefore, we
|
|
||||||
> have designed this version of the GPL to prohibit the practice for those
|
|
||||||
> products. If such problems arise substantially in other domains, we
|
|
||||||
> stand ready to extend this provision to those domains in future versions
|
|
||||||
> of the GPL, as needed to protect the freedom of users.
|
|
||||||
>
|
|
||||||
> Finally, every program is threatened constantly by software patents.
|
|
||||||
> States should not allow patents to restrict development and use of
|
|
||||||
> software on general-purpose computers, but in those that do, we wish to
|
|
||||||
> avoid the special danger that patents applied to a free program could
|
|
||||||
> make it effectively proprietary. To prevent this, the GPL assures that
|
|
||||||
> patents cannot be used to render the program non-free.
|
|
||||||
>
|
|
||||||
> The precise terms and conditions for copying, distribution and
|
|
||||||
> modification follow.
|
|
||||||

|
|
||||||
> TERMS AND CONDITIONS
|
|
||||||
>
|
|
||||||
> 0. Definitions.
|
|
||||||
>
|
|
||||||
> "This License" refers to version 3 of the GNU General Public License.
|
|
||||||
>
|
|
||||||
> "Copyright" also means copyright-like laws that apply to other kinds of
|
|
||||||
> works, such as semiconductor masks.
|
|
||||||
>
|
|
||||||
> "The Program" refers to any copyrightable work licensed under this
|
|
||||||
> License. Each licensee is addressed as "you". "Licensees" and
|
|
||||||
> "recipients" may be individuals or organizations.
|
|
||||||
>
|
|
||||||
> To "modify" a work means to copy from or adapt all or part of the work
|
|
||||||
> in a fashion requiring copyright permission, other than the making of an
|
|
||||||
> exact copy. The resulting work is called a "modified version" of the
|
|
||||||
> earlier work or a work "based on" the earlier work.
|
|
||||||
>
|
|
||||||
> A "covered work" means either the unmodified Program or a work based
|
|
||||||
> on the Program.
|
|
||||||
>
|
|
||||||
> To "propagate" a work means to do anything with it that, without
|
|
||||||
> permission, would make you directly or secondarily liable for
|
|
||||||
> infringement under applicable copyright law, except executing it on a
|
|
||||||
> computer or modifying a private copy. Propagation includes copying,
|
|
||||||
> distribution (with or without modification), making available to the
|
|
||||||
> public, and in some countries other activities as well.
|
|
||||||
>
|
|
||||||
> To "convey" a work means any kind of propagation that enables other
|
|
||||||
> parties to make or receive copies. Mere interaction with a user through
|
|
||||||
> a computer network, with no transfer of a copy, is not conveying.
|
|
||||||
>
|
|
||||||
> An interactive user interface displays "Appropriate Legal Notices"
|
|
||||||
> to the extent that it includes a convenient and prominently visible
|
|
||||||
> feature that (1) displays an appropriate copyright notice, and (2)
|
|
||||||
> tells the user that there is no warranty for the work (except to the
|
|
||||||
> extent that warranties are provided), that licensees may convey the
|
|
||||||
> work under this License, and how to view a copy of this License. If
|
|
||||||
> the interface presents a list of user commands or options, such as a
|
|
||||||
> menu, a prominent item in the list meets this criterion.
|
|
||||||
>
|
|
||||||
> 1. Source Code.
|
|
||||||
>
|
|
||||||
> The "source code" for a work means the preferred form of the work
|
|
||||||
> for making modifications to it. "Object code" means any non-source
|
|
||||||
> form of a work.
|
|
||||||
>
|
|
||||||
> A "Standard Interface" means an interface that either is an official
|
|
||||||
> standard defined by a recognized standards body, or, in the case of
|
|
||||||
> interfaces specified for a particular programming language, one that
|
|
||||||
> is widely used among developers working in that language.
|
|
||||||
>
|
|
||||||
> The "System Libraries" of an executable work include anything, other
|
|
||||||
> than the work as a whole, that (a) is included in the normal form of
|
|
||||||
> packaging a Major Component, but which is not part of that Major
|
|
||||||
> Component, and (b) serves only to enable use of the work with that
|
|
||||||
> Major Component, or to implement a Standard Interface for which an
|
|
||||||
> implementation is available to the public in source code form. A
|
|
||||||
> "Major Component", in this context, means a major essential component
|
|
||||||
> (kernel, window system, and so on) of the specific operating system
|
|
||||||
> (if any) on which the executable work runs, or a compiler used to
|
|
||||||
> produce the work, or an object code interpreter used to run it.
|
|
||||||
>
|
|
||||||
> The "Corresponding Source" for a work in object code form means all
|
|
||||||
> the source code needed to generate, install, and (for an executable
|
|
||||||
> work) run the object code and to modify the work, including scripts to
|
|
||||||
> control those activities. However, it does not include the work's
|
|
||||||
> System Libraries, or general-purpose tools or generally available free
|
|
||||||
> programs which are used unmodified in performing those activities but
|
|
||||||
> which are not part of the work. For example, Corresponding Source
|
|
||||||
> includes interface definition files associated with source files for
|
|
||||||
> the work, and the source code for shared libraries and dynamically
|
|
||||||
> linked subprograms that the work is specifically designed to require,
|
|
||||||
> such as by intimate data communication or control flow between those
|
|
||||||
> subprograms and other parts of the work.
|
|
||||||
>
|
|
||||||
> The Corresponding Source need not include anything that users
|
|
||||||
> can regenerate automatically from other parts of the Corresponding
|
|
||||||
> Source.
|
|
||||||
>
|
|
||||||
> The Corresponding Source for a work in source code form is that
|
|
||||||
> same work.
|
|
||||||
>
|
|
||||||
> 2. Basic Permissions.
|
|
||||||
>
|
|
||||||
> All rights granted under this License are granted for the term of
|
|
||||||
> copyright on the Program, and are irrevocable provided the stated
|
|
||||||
> conditions are met. This License explicitly affirms your unlimited
|
|
||||||
> permission to run the unmodified Program. The output from running a
|
|
||||||
> covered work is covered by this License only if the output, given its
|
|
||||||
> content, constitutes a covered work. This License acknowledges your
|
|
||||||
> rights of fair use or other equivalent, as provided by copyright law.
|
|
||||||
>
|
|
||||||
> You may make, run and propagate covered works that you do not
|
|
||||||
> convey, without conditions so long as your license otherwise remains
|
|
||||||
> in force. You may convey covered works to others for the sole purpose
|
|
||||||
> of having them make modifications exclusively for you, or provide you
|
|
||||||
> with facilities for running those works, provided that you comply with
|
|
||||||
> the terms of this License in conveying all material for which you do
|
|
||||||
> not control copyright. Those thus making or running the covered works
|
|
||||||
> for you must do so exclusively on your behalf, under your direction
|
|
||||||
> and control, on terms that prohibit them from making any copies of
|
|
||||||
> your copyrighted material outside their relationship with you.
|
|
||||||
>
|
|
||||||
> Conveying under any other circumstances is permitted solely under
|
|
||||||
> the conditions stated below. Sublicensing is not allowed; section 10
|
|
||||||
> makes it unnecessary.
|
|
||||||
>
|
|
||||||
> 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
|
||||||
>
|
|
||||||
> No covered work shall be deemed part of an effective technological
|
|
||||||
> measure under any applicable law fulfilling obligations under article
|
|
||||||
> 11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
|
||||||
> similar laws prohibiting or restricting circumvention of such
|
|
||||||
> measures.
|
|
||||||
>
|
|
||||||
> When you convey a covered work, you waive any legal power to forbid
|
|
||||||
> circumvention of technological measures to the extent such circumvention
|
|
||||||
> is effected by exercising rights under this License with respect to
|
|
||||||
> the covered work, and you disclaim any intention to limit operation or
|
|
||||||
> modification of the work as a means of enforcing, against the work's
|
|
||||||
> users, your or third parties' legal rights to forbid circumvention of
|
|
||||||
> technological measures.
|
|
||||||
>
|
|
||||||
> 4. Conveying Verbatim Copies.
|
|
||||||
>
|
|
||||||
> You may convey verbatim copies of the Program's source code as you
|
|
||||||
> receive it, in any medium, provided that you conspicuously and
|
|
||||||
> appropriately publish on each copy an appropriate copyright notice;
|
|
||||||
> keep intact all notices stating that this License and any
|
|
||||||
> non-permissive terms added in accord with section 7 apply to the code;
|
|
||||||
> keep intact all notices of the absence of any warranty; and give all
|
|
||||||
> recipients a copy of this License along with the Program.
|
|
||||||
>
|
|
||||||
> You may charge any price or no price for each copy that you convey,
|
|
||||||
> and you may offer support or warranty protection for a fee.
|
|
||||||
>
|
|
||||||
> 5. Conveying Modified Source Versions.
|
|
||||||
>
|
|
||||||
> You may convey a work based on the Program, or the modifications to
|
|
||||||
> produce it from the Program, in the form of source code under the
|
|
||||||
> terms of section 4, provided that you also meet all of these conditions:
|
|
||||||
>
|
|
||||||
> a) The work must carry prominent notices stating that you modified
|
|
||||||
> it, and giving a relevant date.
|
|
||||||
>
|
|
||||||
> b) The work must carry prominent notices stating that it is
|
|
||||||
> released under this License and any conditions added under section
|
|
||||||
> 7. This requirement modifies the requirement in section 4 to
|
|
||||||
> "keep intact all notices".
|
|
||||||
>
|
|
||||||
> c) You must license the entire work, as a whole, under this
|
|
||||||
> License to anyone who comes into possession of a copy. This
|
|
||||||
> License will therefore apply, along with any applicable section 7
|
|
||||||
> additional terms, to the whole of the work, and all its parts,
|
|
||||||
> regardless of how they are packaged. This License gives no
|
|
||||||
> permission to license the work in any other way, but it does not
|
|
||||||
> invalidate such permission if you have separately received it.
|
|
||||||
>
|
|
||||||
> d) If the work has interactive user interfaces, each must display
|
|
||||||
> Appropriate Legal Notices; however, if the Program has interactive
|
|
||||||
> interfaces that do not display Appropriate Legal Notices, your
|
|
||||||
> work need not make them do so.
|
|
||||||
>
|
|
||||||
> A compilation of a covered work with other separate and independent
|
|
||||||
> works, which are not by their nature extensions of the covered work,
|
|
||||||
> and which are not combined with it such as to form a larger program,
|
|
||||||
> in or on a volume of a storage or distribution medium, is called an
|
|
||||||
> "aggregate" if the compilation and its resulting copyright are not
|
|
||||||
> used to limit the access or legal rights of the compilation's users
|
|
||||||
> beyond what the individual works permit. Inclusion of a covered work
|
|
||||||
> in an aggregate does not cause this License to apply to the other
|
|
||||||
> parts of the aggregate.
|
|
||||||
>
|
|
||||||
> 6. Conveying Non-Source Forms.
|
|
||||||
>
|
|
||||||
> You may convey a covered work in object code form under the terms
|
|
||||||
> of sections 4 and 5, provided that you also convey the
|
|
||||||
> machine-readable Corresponding Source under the terms of this License,
|
|
||||||
> in one of these ways:
|
|
||||||
>
|
|
||||||
> a) Convey the object code in, or embodied in, a physical product
|
|
||||||
> (including a physical distribution medium), accompanied by the
|
|
||||||
> Corresponding Source fixed on a durable physical medium
|
|
||||||
> customarily used for software interchange.
|
|
||||||
>
|
|
||||||
> b) Convey the object code in, or embodied in, a physical product
|
|
||||||
> (including a physical distribution medium), accompanied by a
|
|
||||||
> written offer, valid for at least three years and valid for as
|
|
||||||
> long as you offer spare parts or customer support for that product
|
|
||||||
> model, to give anyone who possesses the object code either (1) a
|
|
||||||
> copy of the Corresponding Source for all the software in the
|
|
||||||
> product that is covered by this License, on a durable physical
|
|
||||||
> medium customarily used for software interchange, for a price no
|
|
||||||
> more than your reasonable cost of physically performing this
|
|
||||||
> conveying of source, or (2) access to copy the
|
|
||||||
> Corresponding Source from a network server at no charge.
|
|
||||||
>
|
|
||||||
> c) Convey individual copies of the object code with a copy of the
|
|
||||||
> written offer to provide the Corresponding Source. This
|
|
||||||
> alternative is allowed only occasionally and noncommercially, and
|
|
||||||
> only if you received the object code with such an offer, in accord
|
|
||||||
> with subsection 6b.
|
|
||||||
>
|
|
||||||
> d) Convey the object code by offering access from a designated
|
|
||||||
> place (gratis or for a charge), and offer equivalent access to the
|
|
||||||
> Corresponding Source in the same way through the same place at no
|
|
||||||
> further charge. You need not require recipients to copy the
|
|
||||||
> Corresponding Source along with the object code. If the place to
|
|
||||||
> copy the object code is a network server, the Corresponding Source
|
|
||||||
> may be on a different server (operated by you or a third party)
|
|
||||||
> that supports equivalent copying facilities, provided you maintain
|
|
||||||
> clear directions next to the object code saying where to find the
|
|
||||||
> Corresponding Source. Regardless of what server hosts the
|
|
||||||
> Corresponding Source, you remain obligated to ensure that it is
|
|
||||||
> available for as long as needed to satisfy these requirements.
|
|
||||||
>
|
|
||||||
> e) Convey the object code using peer-to-peer transmission, provided
|
|
||||||
> you inform other peers where the object code and Corresponding
|
|
||||||
> Source of the work are being offered to the general public at no
|
|
||||||
> charge under subsection 6d.
|
|
||||||
>
|
|
||||||
> A separable portion of the object code, whose source code is excluded
|
|
||||||
> from the Corresponding Source as a System Library, need not be
|
|
||||||
> included in conveying the object code work.
|
|
||||||
>
|
|
||||||
> A "User Product" is either (1) a "consumer product", which means any
|
|
||||||
> tangible personal property which is normally used for personal, family,
|
|
||||||
> or household purposes, or (2) anything designed or sold for incorporation
|
|
||||||
> into a dwelling. In determining whether a product is a consumer product,
|
|
||||||
> doubtful cases shall be resolved in favor of coverage. For a particular
|
|
||||||
> product received by a particular user, "normally used" refers to a
|
|
||||||
> typical or common use of that class of product, regardless of the status
|
|
||||||
> of the particular user or of the way in which the particular user
|
|
||||||
> actually uses, or expects or is expected to use, the product. A product
|
|
||||||
> is a consumer product regardless of whether the product has substantial
|
|
||||||
> commercial, industrial or non-consumer uses, unless such uses represent
|
|
||||||
> the only significant mode of use of the product.
|
|
||||||
>
|
|
||||||
> "Installation Information" for a User Product means any methods,
|

|
|

>
|
|
||||||
> "Additional permissions" are terms that supplement the terms of this
|
|
||||||
> License by making exceptions from one or more of its conditions.
|
|
||||||
> Additional permissions that are applicable to the entire Program shall
|
|
||||||
> be treated as though they were included in this License, to the extent
|
|
||||||
> that they are valid under applicable law. If additional permissions
|
|
||||||
> apply only to part of the Program, that part may be used separately
|
|
||||||
> under those permissions, but the entire Program remains governed by
|
|
||||||
> this License without regard to the additional permissions.
|
|
||||||
>
|
|
||||||
> When you convey a copy of a covered work, you may at your option
|
|
||||||
> remove any additional permissions from that copy, or from any part of
|
|
||||||
> it. (Additional permissions may be written to require their own
|
|
||||||
> removal in certain cases when you modify the work.) You may place
|
|
||||||
> additional permissions on material, added by you to a covered work,
|
|
||||||
> for which you have or can give appropriate copyright permission.
|
|
||||||
>
|
|
||||||
> Notwithstanding any other provision of this License, for material you
|
|
||||||
> add to a covered work, you may (if authorized by the copyright holders of
|
|
||||||
> that material) supplement the terms of this License with terms:
|
|
||||||
>
|
|
||||||
> a) Disclaiming warranty or limiting liability differently from the
|
|
||||||
> terms of sections 15 and 16 of this License; or
|
|
||||||
>
|
|
||||||
> b) Requiring preservation of specified reasonable legal notices or
|
|
||||||
> author attributions in that material or in the Appropriate Legal
|
|
||||||
> Notices displayed by works containing it; or
|
|
||||||
>
|
|
||||||
> c) Prohibiting misrepresentation of the origin of that material, or
|
|
||||||
> requiring that modified versions of such material be marked in
|
|
||||||
> reasonable ways as different from the original version; or
|
|
||||||
>
|
|
||||||
> d) Limiting the use for publicity purposes of names of licensors or
|
|
||||||
> authors of the material; or
|
|
||||||
>
|
|
||||||
> e) Declining to grant rights under trademark law for use of some
|
|
||||||
> trade names, trademarks, or service marks; or
|
|
||||||
>
|
|
||||||
> f) Requiring indemnification of licensors and authors of that
|
|
||||||
> material by anyone who conveys the material (or modified versions of
|
|
||||||
> it) with contractual assumptions of liability to the recipient, for
|
|
||||||
> any liability that these contractual assumptions directly impose on
|
|
||||||
> those licensors and authors.
|
|
||||||
>
|
|
||||||
> All other non-permissive additional terms are considered "further
|
|
||||||
> restrictions" within the meaning of section 10. If the Program as you
|
|
||||||
> received it, or any part of it, contains a notice stating that it is
|
|
||||||
> governed by this License along with a term that is a further
|
|
||||||
> restriction, you may remove that term. If a license document contains
|
|
||||||
> a further restriction but permits relicensing or conveying under this
|
|
||||||
> License, you may add to a covered work material governed by the terms
|
|
||||||
> of that license document, provided that the further restriction does
|
|
||||||
> not survive such relicensing or conveying.
|
|
||||||
>
|
|
||||||
> If you add terms to a covered work in accord with this section, you
|
|
||||||
> must place, in the relevant source files, a statement of the
|
|
||||||
> additional terms that apply to those files, or a notice indicating
|
|
||||||
> where to find the applicable terms.
|
|
||||||
>
|
|
||||||
> Additional terms, permissive or non-permissive, may be stated in the
|
|
||||||
> form of a separately written license, or stated as exceptions;
|
|
||||||
> the above requirements apply either way.
|
|
||||||
>
|
|
||||||
> 8. Termination.
|
|
||||||
>
|
|
||||||
> You may not propagate or modify a covered work except as expressly
|
|
||||||
> provided under this License. Any attempt otherwise to propagate or
|
|
||||||
> modify it is void, and will automatically terminate your rights under
|
|
||||||
> this License (including any patent licenses granted under the third
|
|
||||||
> paragraph of section 11).
|
|
||||||
>
|
|
||||||
> However, if you cease all violation of this License, then your
|
|
||||||
> license from a particular copyright holder is reinstated (a)
|
|
||||||
> provisionally, unless and until the copyright holder explicitly and
|
|
||||||
> finally terminates your license, and (b) permanently, if the copyright
|
|
||||||
> holder fails to notify you of the violation by some reasonable means
|
|
||||||
> prior to 60 days after the cessation.
|
|
||||||
>
|
|
||||||
> Moreover, your license from a particular copyright holder is
|
|
||||||
> reinstated permanently if the copyright holder notifies you of the
|
|
||||||
> violation by some reasonable means, this is the first time you have
|
|
||||||
> received notice of violation of this License (for any work) from that
|
|
||||||
> copyright holder, and you cure the violation prior to 30 days after
|
|
||||||
> your receipt of the notice.
|
|
||||||
>
|
|
||||||
> Termination of your rights under this section does not terminate the
|
|
||||||
> licenses of parties who have received copies or rights from you under
|
|
||||||
> this License. If your rights have been terminated and not permanently
|
|
||||||
> reinstated, you do not qualify to receive new licenses for the same
|
|
||||||
> material under section 10.
|
|
||||||
>
|
|
||||||
> 9. Acceptance Not Required for Having Copies.
|
|
||||||
>
|
|
||||||
> You are not required to accept this License in order to receive or
|
|
||||||
> run a copy of the Program. Ancillary propagation of a covered work
|
|
||||||
> occurring solely as a consequence of using peer-to-peer transmission
|
|
||||||
> to receive a copy likewise does not require acceptance. However,
|
|
||||||
> nothing other than this License grants you permission to propagate or
|
|
||||||
> modify any covered work. These actions infringe copyright if you do
|
|
||||||
> not accept this License. Therefore, by modifying or propagating a
|
|
||||||
> covered work, you indicate your acceptance of this License to do so.
|
|
||||||
>
|
|
||||||
> 10. Automatic Licensing of Downstream Recipients.
|
|
||||||
>
|
|
||||||
> Each time you convey a covered work, the recipient automatically
|
|
||||||
> receives a license from the original licensors, to run, modify and
|
|
||||||
> propagate that work, subject to this License. You are not responsible
|
|
||||||
> for enforcing compliance by third parties with this License.
|
|
||||||
>
|
|
||||||
> An "entity transaction" is a transaction transferring control of an
|
|
||||||
> organization, or substantially all assets of one, or subdividing an
|
|
||||||
> organization, or merging organizations. If propagation of a covered
|
|
||||||
> work results from an entity transaction, each party to that
|
|
||||||
> transaction who receives a copy of the work also receives whatever
|
|
||||||
> licenses to the work the party's predecessor in interest had or could
|
|
||||||
> give under the previous paragraph, plus a right to possession of the
|
|
||||||
> Corresponding Source of the work from the predecessor in interest, if
|
|
||||||
> the predecessor has it or can get it with reasonable efforts.
|
|
||||||
>
|
|
||||||
> You may not impose any further restrictions on the exercise of the
|
|
||||||
> rights granted or affirmed under this License. For example, you may
|
|
||||||
> not impose a license fee, royalty, or other charge for exercise of
|
|
||||||
> rights granted under this License, and you may not initiate litigation
|
|
||||||
> (including a cross-claim or counterclaim in a lawsuit) alleging that
|
|
||||||
> any patent claim is infringed by making, using, selling, offering for
|
|
||||||
> sale, or importing the Program or any portion of it.
|
|
||||||
>
|
|
||||||
> 11. Patents.
|
|
||||||
>
|
|
||||||
> A "contributor" is a copyright holder who authorizes use under this
|
|
||||||
> License of the Program or a work on which the Program is based. The
|
|
||||||
> work thus licensed is called the contributor's "contributor version".
|
|
||||||
>
|
|
||||||
> A contributor's "essential patent claims" are all patent claims
|
|
||||||
> owned or controlled by the contributor, whether already acquired or
|
|
||||||
> hereafter acquired, that would be infringed by some manner, permitted
|
|
||||||
> by this License, of making, using, or selling its contributor version,
|
|
||||||
> but do not include claims that would be infringed only as a
|
|
||||||
> consequence of further modification of the contributor version. For
|
|
||||||
> purposes of this definition, "control" includes the right to grant
|
|
||||||
> patent sublicenses in a manner consistent with the requirements of
|
|
||||||
> this License.
|
|
||||||
>
|
|
||||||
> Each contributor grants you a non-exclusive, worldwide, royalty-free
|

|
|

# DEPRECATED!
|
|
||||||
|
|
||||||
This repository has not been updated for a while!
|
|
||||||
If You are interested in replicating results for [1712.07167](https://arxiv.org/abs/1712.07167) please check [these instruction](https://kalmar.faculty.wmi.amu.edu.pl/post/1712.07176/)
|
|
||||||
Also [this notebook](https://nbviewer.jupyter.org/gist/kalmarek/03510181bc1e7c98615e86e1ec580b2a) could be of some help. If everything else fails the [zenodo dataset](https://zenodo.org/record/1133440) should contain the last-resort instructions.
|
|
||||||
|
|
||||||
This repository contains some legacy code for computations in [Certifying Numerical Estimates of Spectral Gaps](https://arxiv.org/abs/1703.09680).
|
|
||||||
|
|
||||||
# Installing
|
|
||||||
To run the code You need `julia-v0.5` (should work on `v0.6`, but with warnings).
|
|
||||||
You also need to install julia packages: `Nemo-v0.6.3`, `ArgParse`. To do so in `julia`'s REPL run:
|
|
||||||
```julia
|
|
||||||
Pkg.update()
|
|
||||||
Pkg.add("Nemo")
|
|
||||||
Pkg.add("ArgParse")
|
|
||||||
```
|
|
||||||
Then clone the main repository of `Groups.jl`, `GroupRings.jl` and `PropertyT.jl`:
|
|
||||||
```julia
|
|
||||||
Pkg.clone("https://git.wmi.amu.edu.pl/kalmar/Groups.jl.git")
|
|
||||||
Pkg.clone("https://git.wmi.amu.edu.pl/kalmar/GroupRings.jl.git")
|
|
||||||
Pkg.clone("https://git.wmi.amu.edu.pl/kalmar/PropertyT.jl.git")
|
|
||||||
Pkg.resolve()
|
|
||||||
```
|
|
||||||
This should resolve all dependencies (e.g. install `JuMP`, `SCS`, `IntervalArithmetic`, `JLD`, `Memento`). Exit julia and finally clone this repository:
|
|
||||||
```shell
|
|
||||||
git clone https://git.wmi.amu.edu.pl/kalmar/GroupsWithPropertyT.git
|
|
||||||
cd GroupswithPropertyT
|
|
||||||
```
|
|
||||||
|
|
||||||
# Running
|
|
||||||
|
|
||||||
## Naive implementation
|
|
||||||
|
|
||||||
To check that $\Delta^2-\lambda\Delta$ is not decomposable to a sum of hermitian squares of elements in the ball of radius $2$ in $SL(2,7)$ run
|
|
||||||
```shell
|
|
||||||
julia SL.jl -N 2 -p 7 --radius 2 --iterations 100000
|
|
||||||
```
|
|
||||||
(~30 seconds, depending on hardware). The monotonous decreasing $\lambda$ during the optimisation is in column `pri obj` (or `dua obj`) of `solver.log`.
|
|
||||||
|
|
||||||
Compare this to
|
|
||||||
```shell
|
|
||||||
julia SL.jl -N 2 -p 7 --radius 3 --iterations 100000
|
|
||||||
```
|
|
||||||
which finds $\lambda \geq 0.5857$ and decomposes $\Delta^2-\lambda\Delta$ into sum of $47$ hermitian squares in less than 20 seconds (including certification).
|
|
||||||
|
|
||||||
If You see in the output (or in `full.log`) that the upper end of the interval where $\lVert\Delta^2 - \lambda\Delta - \sum{\xi_i}^*\xi_i\rVert_1$ belongs to is too large (resulting in positive `Floating point distance`, but negative `The Augmentation-projected actual distance`), decrease the `--tol` parameter, e.g.
|
|
||||||
```
|
|
||||||
julia SL.jl -N 2 -p 7 --radius 3 --iterations 100000 --tol 1e-9
|
|
||||||
```
|
|
||||||
to achieve a better estimate (the residuals $\ell_1$-norm should be around $\|B_d(e))\|\cdot tol$)
|
|
||||||
|
|
||||||
## Symmetrization enhanced implementation
|
|
||||||
|
|
||||||
A newer version of the software uses orbit and Wedderburn decomposition to effecitively find a (much) smaller optimisation problem to compute the spectral gap $\lambda$. In particular the solution to the original (naive) optimisation problem can be reconstructed from the solution of the symmetrised one.
|
|
||||||
|
|
||||||
E.g. Run
|
|
||||||
```shell
|
|
||||||
julia SL_orbit.jl -N 4 --radius 2 --upper-bound 1.3
|
|
||||||
```
|
|
||||||
to find (and certify) the spectral gap for $SL(4, \mathbb{Z})$ is at least `1.2999...` in just under $2$ minutes time (for comparison this result requires over `5` hours in the old implementation on the same hardware).
|
|
||||||
|
|
||||||
To replicate the results of _$\operatorname{Aut}(\textbf{F}_5)$ has property (T)_ You neet to run (on a `4`-core CPU)
|
|
||||||
```shell
|
|
||||||
julia ../AutFN_orbit.jl -N 5 --upper-bound 1.2 --iterations 24000000 --cpus 4
|
|
||||||
```
|
|
||||||
|
|
||||||
Note that this computation took more than `12` days and required at least `32`GB of ram (and possible more).
|
|
||||||

# Specific version of [1703.09680](https://arxiv.org/abs/1703.09680)
|
|
||||||
|
|
||||||
To checkout the specific versions of packages used for [Certifying Numerical Estimates of Spectral Gaps](https://arxiv.org/abs/1703.09680) run (inside the cloned `GroupswithPropertyT`)
|
|
||||||
```shell
|
|
||||||
git checkout 1703.09680v1
|
|
||||||
```
|
|
||||||
|
|
||||||
Unfortunately: You need to link `~/.julia/v0.5/GroupRings` to `~/.julia/v0.5/GroupAlgebras` due to change in the name of the package. Then run in `julia`
|
|
||||||
```julia
|
|
||||||
Pkg.checkout("GroupRings", "1703.09680v1")
|
|
||||||
Pkg.checkout("PropertyT", "1703.09680v1")
|
|
||||||
Pkg.resolve()
|
|
||||||
```
|
|
||||||
|
|
||||||
# Specific version of [1712.07167](https://arxiv.org/abs/1712.07167)
|
|
||||||
|
|
||||||
You need to run `julia-0.6`.
|
|
||||||
|
|
||||||
Clone `https://git.wmi.amu.edu.pl/kalmar/GroupsWithPropertyT` and checkout the `1712.07167` branch:
|
|
||||||
```
|
|
||||||
git clone https://git.wmi.amu.edu.pl/kalmar/GroupsWithPropertyT.git
|
|
||||||
cd ./GroupsWithPropertyT
|
|
||||||
git checkout 1712.07167
|
|
||||||
```
|
|
||||||
|
|
||||||
In `julia`s REPL execute
|
|
||||||
```julia
|
|
||||||
Pkg.add("ArgParse")
|
|
||||||
Pkg.add("Nemo")
|
|
||||||
Pkg.clone("https://git.wmi.amu.edu.pl/kalmar/Groups.jl.git")
|
|
||||||
Pkg.checkout("Groups", "1712.07167")
|
|
||||||
Pkg.clone("https://git.wmi.amu.edu.pl/kalmar/GroupRings.jl.git")
|
|
||||||
Pkg.checkout("GroupRings", "1712.07167")
|
|
||||||
Pkg.clone("https://git.wmi.amu.edu.pl/kalmar/PropertyT.jl.git")
|
|
||||||
Pkg.checkout("PropertyT", "1712.07167")
|
|
||||||
Pkg.checkout("SCS")
|
|
||||||
Pkg.build("SCS")
|
|
||||||
```
|
|
||||||
|
|
||||||
This should resolve all the dependencies. Quit `julia` and place the `oSAutF5_r2` folder downloaded from [here](https://cloud.impan.pl/s/fGIpxvxdTYYkUxK) inside `GroupsWithPropertyT` folder. To verify the decomposition of $\Delta^2 - \lambda \Delta$ for the group run (if You have a `4`-core CPU at Your disposal)
|
|
||||||
```julia
|
|
||||||
julia AutFN_orbit.jl -N 5 --upper-bound=1.2 --cpus 4
|
|
||||||
```
|
|
||||||
If You want to generate `pm` and other files on Your own delete everything from the `oSAutF5_r2` folder but `1.2` folder and its contents and run the same command again.
|
|
||||||
|
|
||||||
Note: You need at least `32`GB of RAM and spare `24`h of Your CPU.

Implements elements of a semidirect product of groups H and N, where N is normal in the product. Usually written as H ⋉ N.

The multiplication inside semidirect product is defined as
