(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…
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…
Cyclic homology of cleft extensions of algebras
Jorge A. Guccione, Juan J. Guccione, Christian Valqui
Let k be a commutative algebra with the field of the rational numbers included in k and let (E,p,i) be a cleft extension of A. We obtain a new mixed complex, simpler than the canon…
Cyclic homology of braided Hopf crossed products
Graciela Carboni, Jorge A. Guccione, Juan J. Guccione +1
Let k be a field, A a unitary associative k-algebra and V a k-vector space endowed with a distinguished element 1_V. We obtain a mixed complex, simpler that the canonical one, that…
