2009 REU on Combinatorics of Affine Reflection Groups

Participants:

Affine reflection groups are infinite groups that are finitely generated by reflections. Their structure turns out to be related to many topics in modern abstract algebra and representation theory. In this REU, we seek to understand their algebraic properties using combinatorial models and results that generalize those of the the classical symmetric groups and affine symmetric groups.

See the REU notes for more details.
See also the slides from a talk for undergraduates about the affine symmetric group.
