This package is concerned with sum of squares decompositions in group rings of finitely presented groups.
Please have a look into [test](https://github.com/kalmarek/GroupRings.jl/blob/master/test/runtests.jl) directory to see how to use this package. For an example applications have a look at our papers:
[1703.09680](https://arxiv.org/abs/1703.09680), [1712.07167](https://arxiv.org/abs/1712.07167) and [1812.03456](https://arxiv.org/abs/1812.03456).
