Title: q-Whittaker functions, finite fields, and Jordan forms

Speaker: Steven Karp Affiliation: UQAM Zoom: Contact Steve Melczer

Abstract:

The q-Whittaker symmetric function associated to an integer partition is a q-analogue of the Schur symmetric function. We give a new formula for the q-Whittaker function in terms of partial flags compatible with a nilpotent endomorphism over the finite field of size 1/q.
