On the faithfulness of parabolic cohomology as a Hecke module over a finite field

open access: yes, 2006
In this article we prove conditions under which a certain parabolic group cohomology space over a finite field F is a faithful module for the Hecke algebra of Katz modular forms over an algebraic closure of F. These results can e.g.
