Salim Rostam (Universite de Versailles Saint-Quentin-en-Yvelines) Friday 4 August, 12-1pm, Place: Carslaw 375 Title: A KLR-like presentation for the Hecke algebra of G(r,p,n) Abstract: The Hecke algebra of G(r,p,n) can be seen as the fixed point subalgebra of the Hecke algebra of G(r,1,n) (also known as the Ariki-Koike algebra) for a certain automorphism sigma. Using an isomorphism of Brundan and Kleshchev with a KLR algebra, we find an analogue of sigma defined from the KLR presentation. Moreover, it turns out that we can give a KLR-like presentation of the fixed point subalgebra.
