On the Galois module structure of minus class groups
Cornelius Greither, Takenori Kataoka
The main object of this paper is the minus class groups associated to CM-fields as Galois modules. In a previous article of the authors, we introduced a notion of equivalence for m…

The Galois module structure of l-adic realizations of Picard 1-motives and applications
Cornelius Greither, Cristian D. Popescu
We show that the l-adic realizations of certain Picard 1-motives associated to a G-Galois cover of smooth, projective curves defined over an algebraically closed field are G-cohomo…
