Cyclic homology of Hopf Galois extensions and Hopf algebras

P. Jara, D. Stefan

Let H be a Hopf algebra. By definition a modular crossed H-module is a vector space M on which H acts and coacts in a compatible way. To every modular crossed H-module M we associa…

Local--Global Properties for Semistar Operations

Marco Fontana, Pascual Jara, Eva Santos

We study the "local" behavior of several relevant properties concerning semistar operations, like finite type, stable, spectral, e.a.b. and a.b. We deal with the "global" problem o…

Prüfer --multiplication domains and semistar operations

Marco Fontana, Pascual Jara, Eva Santos

We prove a characterization of a PMD, when is a semistar operation, in terms of polynomials (by using the classical characterization of Prüfer domains, in terms of p…
