"In mathematics, Hochschild homology (and cohomology) is a homology theory for associative algebras over rings. There is also a theory for Hochschild homology of certain functors. Hochschild cohomology was introduced by Gerhard Hochschild (1945) for algebras over a field, and extended to algebras over … See more Let k be a field, A an associative k-algebra, and M an A-bimodule. The enveloping algebra of A is the tensor product $${\displaystyle A^{e}=A\otimes A^{o}}$$ of A with its opposite algebra. Bimodules over A are essentially … See more The examples of Hochschild homology computations can be stratified into a number of distinct cases with fairly general theorems describing the structure of the homology groups … See more • Cyclic homology See more The simplicial circle $${\displaystyle S^{1}}$$ is a simplicial object in the category $${\displaystyle \operatorname {Fin} _{*}}$$ of finite pointed sets, i.e., a functor $${\displaystyle \Delta ^{o}\to \operatorname {Fin} _{*}.}$$ Thus, if F is a functor See more The above construction of the Hochschild complex can be adapted to more general situations, namely by replacing the category of (complexes of) $${\displaystyle k}$$-modules by an ∞-category (equipped with a tensor product) $${\displaystyle {\mathcal {C}}}$$, … See more Introductory articles • Dylan G.L.
