Title: Symmetry of the Mackey Algebra
Abstract:
Let \(G\) be a finite group. Let \(R\) be a commutative ring. The Mackey algebra and the group algebra share a lot of properties. However, while the group algebra is always symmetric, this is not the case of the Mackey algebra.
In this talk we present a systematic approach to the question of the symmetry of the Mackey algebra. Using tools of monoidal categories this question is reduced to a question on the usual Burnside ring.
