Equivariant cyclic homology and equivariant differential forms
Étale descent for Hochschild and cyclic homology.
Excision in entire cyclic cohomology
We prove that entire and periodic cyclic cohomology satisfy excision for extensions of bornological algebras with a bounded linear section. That is, for such an extension we obtain a six term exact sequence in cohomology.
