Decomposable Specht Modules Indexed by Bihooks II
Decomposable Specht Modules Indexed by Bihooks II
Abstract Previously, the last two authors found large families of decomposable Specht modules labelled by bihooks, over the Iwahoriā€“Hecke algebra of type B . In most cases we conjectured that these were the only decomposable Specht modules labelled by bihooks, proving it in some instances. Inspired by a recent semisimplicity ā€¦
