The weak Lefschetz property for artinian Gorenstein algebras

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 3211-3222, October 2025.
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.

Artinian band sums of rings

open access: yes, 1995
Band sums of associative rings were introduced by Weissglass in 1973. The main theorem claims that the support of every Artinian band sum of rings is finite. This result is analogous to the well-known theorem on Artinian semigroup rings.

Holomorphic field theories and higher algebra

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
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 ...

Artinian skew group rings

open access: yes, 1979
Let R be a ring with identity and let θ \theta be a group homomorphism from a group G to Aut ( R ) {\operatorname {Aut}}(R) , the group of automorphisms of R.

Cotilting Duality for Artinian Rings

open access: yes
A classical result due to Morita and Azumaya establishes that given two arbitrary rings, any duality between their finitely generated modules is representable by a faithfully balanced bimodule which is a finitely generated injective cogenerator of both rings and, equivalently, these latter are one-sided artinian. We extend this well-known result to the

On Some Classes of Artinian Rings

open access: yesJournal of Algebra, 2000
The authors study certain classes of Artinian rings whose modules have nice decomposition properties. It is shown that if every countably generated right \(R\)-module is the direct sum of a projective module and a CS-module (i.e., a module with all complements being direct summands), then \(R\) is right Artinian with Jacobson radical cube zero.

On metric dimension and crosscap analysis of sum-annihilating essential ideal graph of commutative rings

open access: yesJournal of Taibah University for Science
Consider a commutative ring with unity denoted as [Formula: see text]. An ideal I of a ring [Formula: see text] is called an annihilating ideal if there exists a non-zero element [Formula: see text] such that rI = 0.

On completely 0-simple semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Let S be a completely 0-simple semigroup and F be an algebraically closed field. Then for each 0-minimal right ideal M of S, M=B∪C∪{0}, where B is a right group and C is a zero semigroup.
