** September 27:**

**Speaker: ** Raphaël Rouquier, UCLA

**Title:**
Higher representation theory

**Abstract: **
Representation theory is the study of vector spaces with prescribed symmetries.
Replacing vector spaces by more complicated structures (of categorical, topological or
geometrical origin) leads to new directions in algebra. This sheds a new
light on geometric representation theory. More general moduli spaces constructions
and enumerative invariants should fit in that framework. An additional motivation
is the construction of invariants of low-dimensional manifolds from quantum field
theories.
