Several representations of my favorite open problem

How many commutation classes does the longest element in the symmetric group have? I’ll begin by explaining this open problem in the context of Coxeter groups and then discuss several equivalent representations. Time permitting, I will also summarize some recent work with undergraduate Dustin Story on our quest to improve upon the known upper bounds.

This talk was given on February 9, 2016 in the Northern Arizona University Department of Mathematics and Statistics Colloquium.
