EMANUELE DOTTO (RFWU Bonn): Witt vectors, polynomiality, and the dihedral fixed-points of THH

Abstract

I will give a description of the components of the dihedral fixed-points of real topological Hochschild homology in terms of Witt vectors, analogous to the calculation of Hesselholt and Madsen of the components of TR. The Witt vectors functor on commutative rings admits extra functoriality with respect to polynomial maps, that I will use to describe the multiplicative transfers from cyclic to dihedral fixed-points of THH.
This is joint work with Moi and Patchkoria.
