Cohomology and Representations of Finite Group Schemes
Abstract: Understanding modular representations of finite groups, $p$-restricted
Lie algebras and related structures is a central challenge in algebra.
Beginning with work of Daniel Quillen, various mathematicians have
used cohomological techniques to produce geometric structures
which reflect properties of modular represenations. In the past couple
of years, Julia Pevtsova and I have introduced elementary represenation-
theoretic techniques which refine and generalize these cohomological
invariants. In current work with Andrei Suslin, Julia and I use
these techniques to introduce invariants which are new even for very
elementary finite groups.
