Global algebraic K-theory

Algebraic Topology 2022-07-05 v2

Abstract

We introduce a global equivariant refinement of algebraic K-theory; here `global equivariant' refers to simultaneous and compatible actions of all finite groups. Our construction turns a specific kind of categorical input data into a global Ω\Omega-spectrum that keeps track of genuine GG-equivariant infinite loop spaces, for all finite groups GG. The resulting global algebraic K-theory spectrum is a rigid way of packaging the representation K-theory, or `Swan K-theory' into one highly structured object.
