Abstract

For an extension of associative algebras BAB\subset A over a field and an AA-bimodule XX, we obtain a Jacobi-Zariski long nearly exact sequence relating the Hochschild homologies of AA and BB, and the relative Hochschild homology, all of them with coefficients in XX. This long sequence is exact twice in three. There is a spectral sequence which converges to the gap of exactness.

Comments

A typo in the degree of the torsion vector spaces of the first page of the spectral sequence is corrected. The degree where the exact long sequence ends at Theorem 6.5 is therefore updated. To appear in Bulletin of the London Mathematical Society
