Backström algebras

Yuriy A. Drozd

We introduce Backström pairs and Backström rings, study their derived categories and construct for them a sort of categorical resolutions. For the latter we define the global dimen…

Representations and cohomologies of Kleinian 4-rings

Yuriy A. Drozd

We introduce a new class of algebras over discrete valuation rings, called Kleinian 4-rings, which generalize the group algebra of the Kleinian 4-group. For these algebras we descr…

Representations of Munn algebras and related semigroups

Yuriy A. Drozd, Andriana I. Plakosh

We establish representation types (finite, tame or wild) of finite dimensional Munn algebras with semisimple bases. As an application, we establish representation types of finite 0…

Cohomologies of regular lattices over the Kleinian 4-group

Yuriy Drozd, Andriana Plakosh

We calculate explicitly cohomologies of the lattices over the Kleinian 4-group belonging to the regular components of the Auslander-Reiten quiver as well as of their dual modules.…

Rejection lemma and almost split sequences

Yuriy A. Drozd

We study the behaviour of almost split sequences and \art quivers of an order under rejection of bijective modules. In particular, we establish relations of stable categories and a…

Morita theory for non-commutative noetherian schemes

Igor Burban, Yuriy Drozd

In this paper, we study equivalences between the categories of quasi-coherent sheaves on non-commutative noetherian schemes. In particular, give a new proof of Caldararu's conjectu…
