- Lecture 1. Problems in Linear Algebra Related to Root Systems
Abstract: The question of classifying differential equations on the Riemann sphere leads one to consider the following problem in linear algebra: given a collection of conjugacy classes of matrices, determine whether or not there are matrices in these classes whose product is the identity. In his book "Rigid Local Systems", N. Katz gave an algorithm for determining whether or not there is a rigid irreducible solution, and wrote that it "leaves one with the impression that there is a fascinating bestiary waiting to be compiled". I shall explain how this and other bestiaries are controlled by root systems for Kac-Moody Lie algebras.
- Lecture 2. Indecomposable Representations of Quivers
Abstract: There are famous theorems of P. Gabriel and V. Kac describing the indecomposable representations of quivers in terms of root systems. For example, there is a unique indecomposable representation associated to each "real" root. I shall discuss some of the open problems about these representations, and some small progress. This is based partially on work by my student M. Wiedemann.
