(Co)homology of crossed products in weak contexts
Jorge A. Guccione, Juan J. Guccione, Christian Valqui
We obtain a mixed complex simpler than the canonical one the computes the type cyclic homologies of a crossed product with invertible cocycle , of a weak module alge…

Cleft extensions of weak Hopf algebras
Jorge A. Guccione, Juan J. Guccione, Christian Valqui
In this paper we study the theory of cleft extensions for a weak bialgebra H. Among other results, we determine when two unitary crossed products of an algebra A by H are equivalen…

Bivariant K-theory of generalized Weyl algebras
Christian Valqui, Julio Gutiérrez
We compute the isomorphism class in of all noncommutative generalized Weyl algebras $A=\CC[h](σ, P)$, where is an automorphism of $\CC[h]$, exce…
