1136. Marcin Chalupnik and Piotr Kowalski
Difference modules and difference cohomology
E-mail:

Submission date: 21 December 2016

Abstract:

We give some basics about homological algebra of difference representations. We consider both the difference-discrete and the difference-rational case. We define the corresponding cohomology theories and show the existence of spectral sequences relating these cohomology theories with the standard ones.
