Title: The role of Nichols algebras in the cohomology of finite-dimensional Hopf algebras

Abstract:

I will report on work in progress, joint with Iván Angiono, Julia Pevtsova and Sarah Witherspoon.
It was asked by Friedlander and Suslin whether the cohomology ring of a finite-dimensional Hopf algebra is finitely generated. I will explain our approach to answer affirmatively this question, extending work of several authors.
