Equivariant Hopf Galois extensions and Hopf cyclic cohomology

M. Hassanzadeh, B. Rangipour

We define the notion of equivariant Hopf Galois extension and apply it as a functor between category of SAYD modules of the Hopf algebras involving in the extension. This generaliz…

Cup products in Hopf cyclic cohomology with coefficients in contramodules

Bahram Rangipour

We use stable anti Yetter-Drinfeld contramodules to improve the cup products in Hopf cyclic cohomology. The improvement fixes the lack of functoriality of the cup products previous…
