Semisimplicity of some deformations of the subgroup category and the biset category
Laurence Barker, İsmail Alperen Öğüt
We introduce some deformations of the biset category and prove a semisimplicity property. We also consider another group category, called the subgroup category, whose morphisms are…

Some deformations of the fibred biset category
Laurence Barker, İsmail Alperen Öğüt
We prove the well-definedness of some deformations of the fibred biset category in characteristic zero. The method is to realize the fibred biset category and the deformations as t…
