If you have a question about this talk, please contact Christopher Brookes. The question of which ordinary irreducible representations of the symmetric group remain irreducible in characteristic 2 was solved ten years ago by James and Mathas. Here we consider the generalisation to the Hecke algebra of type A, with q=-1, which continues to resist attempts at a solution. We present a conjecture, and describe work in progress aimed at a proof; this involves realising homomorphisms between Specht modules using the Khovanov-Lauda-Rouquier framework for Hecke algebras.
