Conference: Representations of Symmetric Groups, Hecke Algebras and KLR Algebras

Kleshchev, Mathas and Ram have given a homogeneous presentation for any Specht module for a KLR algebra in type A. The relations include ‘homogeneous Garnir relations’, which appear in a slightly nebulous (and inefficient) form. I’ll describe what happens when the Garnir relations are re-written in terms of standard generators; as we’ll see, some interesting combinatorics related to Dyck tilings comes into play.
