Speaker:

Andrew Mathas (University of Sydney)

Abstract:

Brundan and Kleshchev recently introduced a $$\mathbb{Z}$$-grading on the cyclotomic Hecke algebras of the complex refection groups of type $$G(r,1,n)$$. Brundan, Kleshchev and Wang showed how to define a graded lift of the Specht modules for these algebras over a field. In this talk I will explain what is now known about these modules and why they are important. Finally I will describe a new way of looking at the KLR grading which gives new information about the grading and, in particular, a better basis for the graded Specht modules.

After the seminar we will take the speaker to lunch.
