On the cohomology ring of Frobenius kernels

Frobenius kernels are infinitesimal subgroups of finite group schemes, whose coordinate algebras are finite dimensional and local. These groups play a fundamental role in relating modular cohomology theory of finite groups to that of reductive algebraic groups. In this talk, we will give a survey on the cohomology ring of Frobenius kernels of a classical group and then introduce some results related to cohomological properties of these rings in our recent study.
