Biset transformations of Tambara functors

Category Theory 2013-11-19 v2

Abstract

If we are given an HH-GG-biset UU for finite groups GG and HH, then any Mackey functor on GG can be transformed by UU into a Mackey functor on HH. In this article, we show that the biset transformation is also applicable to Tambara functors when UU is right-free, and in fact forms a functor between the category of Tambara functors on GG and HH. This biset transformation functor is compatible with some algebraic operations on Tambara functors, such as ideal quotients or fractions. In the latter part, we also construct the left adjoint of the biset transformation.
