Abstract

In the previous article 'A Mackey-functor theoretic interpretation of biset functors', we have constructed the 2-category S\mathbb{S} of finite sets with variable finite group actions, in which bicoproducts and bipullbacks exist. As shown in it, biset functors can be regarded as a special class of Mackey functors on S\mathbb{S}. In this article, we equip S\mathbb{S} with a system of adjoint triplets, which satisfies properties analogous to a derivator. This system encodes the six operations for finite groups. As a corollary, we show that the associated Burnside rings satify analogous properties to a Tambara functor, in the context of biset functor theory.
