Algebra Seminar

Graded Specht modules


Friday 1st June, 12:05--12:55pm, Carslaw 175


Andrew Mathas (University of Sydney)


Graded Specht modules


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.

See the Algebra Seminar web page for information about other seminars in the series.
