Colloquium Title and Abstract:

Title: Semi-simplicity in representation theory
Abstract: Representation theory is the study of linear symmetry. Since the first papers on the representation theory of finite groups by Frobenius at the end of the 19th century, the theory has grown to form a fundamental tool of modern pure mathematics, with applications ranging from the standard model in particle physics to the Langlands program in number theory. Some of the most important theorems in representation theory assert some form of semi-simplicity. Examples include Maschke’s theorem on representations of finite groups over the complex numbers (proved in 1897), Weyl’s theorem on representations of compact Lie groups (proved in 1930), and the Kazhdan-Lusztig conjecture (proved by Beilinson-Bernstein and Brylinski-Kashiwara in 1980). The lectures will provide an introduction to these ideas, with an emphasis on our attempts to uncover further layers of hidden semi-simplicity.

Support for travel for UK based PhD students may be available, please contact heilbronn-coordinator@bristol.ac.uk with any requests by 18th March.
