Special Year Seminar

Cohomology of classifying space/stack of a group G is the home which resides all characteristic classes of G-bundles/torsors. In this talk, we will try to explain some results on Hodge/de Rham cohomology of BG where G is a $p$-power order commutative group scheme over a perfect field of characteristic $p$, in terms of its Dieudonné module.

This is a joint work in progress with Dmitry Kubrak and Shubhodip Mondal.
