Decomposable Specht modules for Hecke algebras

In this talk, I will give a brief overview of decomposable Specht modules for the symmetric group and its Hecke algebra deformation. I will then cover joint work with Liron Speyer on the decomposability of Specht modules indexed by bihooks for the Hecke algebra of type B from the perspective of the cyclotomic KLR algebra. Finally, if time permits, I will close with our currrent work on determining the structure of these decomposable Specht modules.
