Loday constructions of Tambara functors

Abstract

Building on work of Hill, Hoyer and Mazur we propose an equivariant version of a Loday construction for GG-Tambara functors where GG is an arbitrary finite group. For any finite simplicial GG-set and any GG-Tambara functor, our Loday construction is a simplicial GG-Tambara functor. We study its properties and examples. For a circle with rotation action by a finite cyclic group our construction agrees with the twisted cyclic nerve of Blumberg, Gerhardt, Hill, and Lawson. We also show how the Loday construction for genuine commutative GG-ring spectra relates to our algebraic one via the π0\underline{\pi}_0-functor. We describe Real topological Hochschild homology as such a Loday construction.
