MATH 3094 - Section 1: Combinatorics of Coxeter Groups

Description: A Coxeter group is a collection of "symmetries" that have properties similar to mirror reflections. The theory of Coxeter groups is a fundamental and active area of research, with a beautiful interplay of algebraic, combinatorial, and geometric ideas. The symmetric group, i.e., permutations of n objects, is one of the most basic examples; many facts about its structure have interesting generalizations to more general Coxeter groups.

This course will provide a gentle introduction to the theory of reflection groups and Coxeter groups from a combinatorial point of view. We will review necessary background from linear algebra and group theory and apply them to topics such as root systems, Bruhat order, reduced words, and classiffcations of finite reflection groups. While the course is primarily targeted at mathematics students, the subject matter would be of interest (and possible use) in the natural sciences.

After the basic material is covered, we will draw some connections to current research topics in algebraic combinatorics.
