Özet

We prove that for an inclusion of unital associative but not necessarily commutative k-algebras B subset of A we have long exact sequences in Hochschild homology and cyclic (co)homology akin to the Jacobi-Zariski sequence in Andre-Quillen homology, provided that the quotient B-module AIB is flat. We also prove that for an arbitrary r-flat morphism phi: B -> A with an H-unital kernel, one can express the Wodzicki excision sequence and our Jacobi-Zariski sequence in Hochschild homology and cyclic (co)homology as a single long exact sequence.
