Universal extension classes for $G L_{2}$

Christopher M. Drupieski

In this note we give a new existence proof for the universal extension classes for $G L_{2}$ previously constructed by Friedlander and Suslin via the theory of strict polynomial funct…

Bounding the dimensions of rational cohomology groups

Christopher P. Bendel, Brian D. Boe, Christopher M. Drupieski +4

Let $k$ be an algebraically closed field of characteristic $p > 0$ , and let $G$ be a simple simply-connected algebraic group over $k$ that is defined and split over the prime field…

Cohomological finite generation for restricted Lie superalgebras and finite supergroup schemes

Christopher M. Drupieski

We prove that the cohomology ring of a finite-dimensional restricted Lie superalgebra over a field of characteristic $p > 2$ is a finitely-generated algebra. Our proof makes essent…
