Description:


The goal of this session is to bring together researchers with interests in combinatorial Lie theory. Lie theory provides a common language, and collection of combinatorial and geometric tools, with which to study many seemingly different areas of mathematical research: representation theory, algebraic combinatorics, and algebraic geometry
