Difference modules and difference cohomology

Algebraic Geometry 2018-11-07 v2

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.
