 Topological Hochschild homology

Topological Hochschild homology (THH) is a concept from algebraic topology and homotopy theory that extends classical Hochschild homology to the setting of topological spaces, particularly focusing on categories associated with topological rings and algebras. It offers a way to study the "homotopy-theoretic" properties of certain algebraic structures via topological methods. ### Key Concepts 1.
