The main purpose of this note is to construct a divisorial version of the Chase-Harrison- Rosenberg exact sequence, thus reducing the calculation of involutive invariants of a Krull domain to that of certain Amitsur and Galois cohomology groups.

We introduce noncommutative sites over a quantale, the so-called Q-sites, and define appropriate presheaves and sheaves over these. We show how most of the technical machinery which allows to construct sheaves associated to arbitrary presheaves in th

In this note, we introduce the notion of multispectrum over a local monoid. We define inductive limits of multispectra and derive their main properties.

In this note, we study the functorial behaviour of the hermitian Picard group with respect to centrally induced ring morphisms. As an application, we construct Mayer-Vietoris sequences which provide an efficient tool to concretely calculate the hermi

In this note, we will calculate for algebras, which are module-finite over their noetherian center, the stalks of the structure sheaves previously constructed in [2].

In this text, we introduce and study involutive class groups and Brauer groups of a Krull domain R. We derive some exact sequences, connecting these groups and linking them to classical invariants, thus allowing to calculate them in concrete situatio

In this note, we introduce the relative hermitian Picard group of a torsion triple. Unlike the situation in the absolute case, the modules on which this group is based are no longer finitely generated nor projective. In order to compensate for this,

In this paper, we introduce strongly normalizing extensions as a natural generalization of centralizing extensions between rings. We show that these extensions behave in a much nicer way than normalizing extensions, both from the geometric and locali
