Talk by Dr. Ryan Grady (Mathematical Sciences, MSU)

2/10/2020  4:10-5:00pm  Wilson Hall 1-144



In this S\'{e}minaire Bourbaki style talk, I will give an overview of some recent work of Sam Gunningham and collaborators.  In particular, I will talk about the construction of a family of 2D Topological Field Theorys (TFTs) which categorify the representation theory of algebraic groups.  In a related setting, we will also discuss the integration of Hamiltonian flows on a $G$-space, for $G$ a complex reductive group. Much of the talk will be spent discussing background/providing context for these results.
