Victor Reiner (Minnesota) 10-11hTitle: Combining q-analogues and t-analogues
Abstract. Together with my colleagues Dennis Stanton and Joel Lewis, we have found severalresults for the symmetric group S_n having q-analogues for the general linear group GL( n, F_q ). Often the symmetric group result also has a t-analogue, where t is now a grading variable coming from invariant theory, and the q-analogue becomes a (q,t)-analogue for GL( n , F_q ). Here the q and the t play asymmetric roles! This talk will discuss some theorems of this nature, along with some conjectures. Thomas Lam (Michigan) 11:30h-12:30hTitle: Dimers and the canonical basis
