Feb 21, 2017 at 22:07 | comment | added | Mare | sorry, I think I did not wait long enough. It might be that the syzygies grow very slowly and I didnt wait long enough. So I think the dimensions are not bounded (but it really looked like that calculating syzygies till 100). | |
Feb 21, 2017 at 21:26 | comment | added | Mare | Taking the Nakayama (quiver) algebra with kupisch series ([3,3,3,3,3,3,3,2,1] and then its trivial extension, my Pc suggests it has a simple module with bounded Omegas but which is not periodic. It is over a finite field with characteristic 3, but I think that it does not matter what the field is for that example, since the relations are field independent. | |
