Artinian Semigroup-Graded Rings

Bulletin of the London Mathematical Society, 1995
Let \(S\) be a semigroup with no infinite subgroups and let \(R\) be a right Artinian \(S\)-graded ring. We prove that \(R\) necessarily has finite support.

Semigroup rings over semiprime ring semigroups

2019
We consider semigroup rings over a particular class of semigroups: those semigroups which arise as the multiplicative semigroup of a ring.

Technique of semigroup ring theory: Regular semigroup rings

Journal of Mathematical Sciences, 1999
Let \(S\) be a semigroup and \(G\) a subgroup of \(S\). Let \(R\) be a ring (perhaps, without unity) and \(R'\) a subring of \(R\). The author gives connections between properties of the group ring \(RG\) and the semigroup ring \(RS\), and also the semigroup rings \(RS\) and \(R'S\).

Coinduction for semigroup-graded rings

Communications in Algebra, 1999
We describe the graded-simple modules over a semigroup-graded ring in terms of the simple modules over various component subrings. Our method utilizes the coinduction functors Coindx .

Semigroups and rings

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1978
In a previous publication [1] we considered the structure of a fragmented ring and of its multiplicative semigroup. In the present publication we consider, in a purely semigroup-theoretic context, some ideas related to those in [1]. As shown by an example, the semigroups we consider need not be the multiplicative semigroup of a ring.

Semigroup Rings of Completely Regular Semigroups

1990
A semigroup S is said to be completely regular if and only if it is covered by its subgroups; that is, if and only if, for each a ∈ S, a ∈ a2 S∩S a2. Groups and bands (semigroups of idempotents) are extreme special cases. In this paper a survey is given of results on the Jacobson radical of the semigroup ring of a completely regular semigroup over a ...
