Algebra Seminar: Mathas -- Alternating Hecke algebras

Andrew Mathas (University of Sydney) 

Friday 13 May, 12-1pm, Place: Carslaw 375 

Alternating Hecke algebras 

The alternating Hecke algebras are fixed-point subalgebras of the Iwahori-Hecke algebra
of the symmetric groups, which include the group algebras of the alternating groups as a
special case.  I will give an overview of the representation theory of these algebras,
including their character theory and a KLR grading on these algebras.  

This is based on joint work my my students Leah Neaves and Clinton Boys.
