*Topological generalizations of Hochschild homology*

### Abstract

After reviewing the definition of Hochschild homology, I will outline
how this theory can be generalized by allowing the sphere spectrum of
stable homotopy theory as a ground ring. The resulting topological
Hochschild homology is useful because it receives a trace map from
algebraic K-theory, and I will present both computations and
structural results for topological Hochschild homology and some of its
refinements.
