DESCRIPTION:Ivo Dell'Ambrogio (Université de Lille)\n(Joint work with Pau
 l Balmer.) We propose a categorification of the notion of Mackey functor f
 or finite groups\, intended to capture "higher" equivariant phenomena occu
 rring throughout mathematics which are invisible to ordinary Mackey functo
 rs. Examples of such structures include familiar equivariant objects such 
 as: (abelian and derived) categories of linear group representations\, sta
 ble module categories\, equivariant topological spectra\, equivariant KK-t
 heory of C*-algebras\, etc. Among the phenomena covered we find: ambidexte
 rity (a.k.a. Wirthmüller isomophisms)\, the separable monadicity of restr
 iction functors\, block decompositions\, etc.  In this talk I will motiva
 te our axioms with examples and explain the first results of the theory.
