If you have a question about this talk, please contact Chris Parker.

We investigate the cohomology of finite Chevalley groups in cross characteristic and use results of Guralnick and Tiep from 2011 on the first cohomology group to obtain a general result for the nth cohomology group. In this talk, we will use these results to completely the determine the cohomology of all irreducible modules for PSL (2,q) when the characteristic of the representation is not 2.
