### Decomposable Specht modules for Hecke algebras

Algebra and Geometry Seminar

12th December 2019, 4:30 pm – 5:30 pm

Fry Building, 2.04

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.
