Recent Work on Various Cohomology Theories
ABSTRACT: I will give a broad overview of my work on various cohomology theories. In particular, I will discuss results on:
1) Cohomology of skew group algebras,
2) Gerstenhaber structure of twisted tensor products, and
3) Stable cohomology of finite dimensional Hopf algebras.
As this is an expository talk, necessary background and motivation will be given.
