Hook fusion procedure for hyper-octahedral groups

Dimpi KM, Geetha Thangavelu

We derive a new expression for the diagonal matrix elements of irreducible representations of the hyperoctahedral group. This expression is obtained using Grime's hook fusion proce…

Comparing cohomology via exact split pairs in diagram algebras

Sulakhana Chowdhury, Geetha Thangavelu

In this article, we compare the cohomology between the categories of modules of the diagram algebras and the categories of modules of its input algebras. Our main result establishe…
