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(Fₙ) becomes trivial under the representation
|
||||||
|
Aut(Fₙ) → GLₙ(ℤ)⋉ℤⁿ → GL_(n+1)(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 (S)Aut(𝔽ₙ)
