symmetric monoidal (∞,1)-category of spectra
Topological Hochschild (resp. topological cyclic, survey is in (May) homology is a refinement of Hochschild homology/cyclic homology from commutative rings/algebras to the higher algebra of ring spectra/E-∞ rings/E-∞ algebras.
In particular, given a ring , then there is a natural morphism of spectra
from the algebraic K-theory spectrum to the topological Hochschild homology spectrum, the Dennis trace map. Since Hochschild homology spectra are naturally cyclotomic spectra, that factors through the topological cyclic homology spectrum via a map called the cyclotomic trace which much like a Chern character map for algebraic K-theory.
The spectra and are typically easier to analyze than . Moreover, the difference between them and is “locally constant” (Dundas-Goodwillie-McCarthy13) and often otherwise bounded in complexity. Accordingly, and are in practice computationally useful approximations to .
There are various generalizations:
Just as for basic Hochschild homology, there is higher topological Hochschild homology (Carlsson-Douglas-Dundas 08) given not just by derived loop spaces but by derived mapping spaces out of higher dimensional tori.
