Classifying thick subcategories over a Koszul complex via the curved BGG correspondence
Abstract In this work, we classify the thick subcategories of the bounded derived category of dg modules over a Koszul complex on any list of elements in a regular ring. This simultaneously recovers a theorem of Stevenson when the list of elements is a regular sequence and the classification of thick subcategories for an exterior algebra over a field ...

Classes of modules closed under projective covers
In this work, we study some classes of modules closed under submodules, quotients, and projective covers, even if the left projective cover of an arbitrary left module not always exists. We obtain a characterization of artinian principal ideal rings when

The weak Lefschetz property for artinian Gorenstein algebras
Abstract It is an extremely elusive problem to determine which standard artinian graded K$K$‐algebras satisfy the weak Lefschetz property (WLP). Codimension 2 artinian Gorenstein graded K$K$‐algebras have the WLP and it is open to what extent such result might work for codimension 3 artinian Gorenstein graded K$K$‐algebras.

Structure of H-semiprime artinian algebras [PDF]
Let H be a Hopf algebra over a field. It is proved that every H-semiprime right artinian left H-module algebra A is quasi-Frobenius and H-semisimple.

Certain Artinian Rings are Noetherian
Throughout this paper the word “ring” will mean an associative ring which need not have an identity element. There are Artinian rings which are not Noetherian, for example C(p∞) with zero

Holomorphic field theories and higher algebra
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Modules over group rings of groups with restrictions on the system of all proper subgroups [PDF]
We consider the class M of R{modules where R is an associative ring. Let A be a module over a group ring RG, G be a group and let L(G) be the set of all proper subgroups of G. We suppose that if H 2 L(G) then A=CA(H) belongs to M. We study an RG{module A

ON THE LATTICE OF LINEAR MODULE TOPOLOGIES
We study various features of the lattice ${\cal L}_M$ of linear module topologies on a module $M$ and their impact on the structure of the abstract module.

STRUCTURE OF THE FLAT COVERS OF ARTINIAN MODULES [PDF]
Summary: The aim of the paper is to obtain information about the flat covers and minimal flat resolutions of Artinian modules over a Noetherian ring. Let \(R\) be a commutative Noetherian ring and let \(A\) be an Artinian \(R\)-module. We prove that the flat cover of \(A\) is of the form \(\prod_{p\in\text{Att}_R(A)}T_p\), where \(T_p\) is the ...
