HYPERIDEALS IN M-POLYSYMMETRICAL HYPERRINGS [PDF]

open access: yesJournal of Algebraic Systems, 2019
An M-polysymmetrical hyperring $(R,+,cdot )$ is an algebraic system, where $(R,+)$ is an M-polysymmetrical hypergroup, $(R,cdot )$ is a semigroup and $cdot$ is bilaterally distributive over $+$.

A Note on Locally Inverse Semigroup Algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
Let R be a commutative ring and S a finite locally inverse semigroup. It is proved that the semigroup algebra R[S] is isomorphic to the direct product of Munn algebras ℳ(R[GJ],mJ,nJ;PJ) with J∈S/𝒥, where mJ is the number of ℛ-classes in J, nJ the

The strong nil-cleanness of semigroup rings

open access: yesOpen Mathematics, 2020
In this paper, we study the strong nil-cleanness of certain classes of semigroup rings. For a completely 0-simple semigroup M=ℳ0(G;I,Λ;P)M={ {\mathcal M} }^{0}(G;I,\text{Λ};P), we show that the contracted semigroup ring R0[M]{R}_{0}{[}M] is ...

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.

Regularity of Semigroup Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
The conditions unlder which a semnigroup ring is regu- lar (in the sense of von Neumann) are inlvestigated. SLufficient con- ditions are obtained in order that the semnigroup ring of an inverse semigroup be regular. Consequences of the regularity of the seni- group ring for the subgroups of the semigroup are established.

An hypervaluation of a ring onto a totally ordered non-cancellative semigroup without zero divisors

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
In this paper we answer to a question posed by Marc KRANSER: It is possible to have a totally ordered noncancellative semigroup without zero divisors, and a ring hypervaluated by this semigroup?

A Characterization of Left Regularity

open access: yesUniversal Journal of Mathematics and Applications, 2019
We show that a zero-symmetric near-ring $N$ is left regular if and only if $N $ is regular and isomorphic to a subdirect product of integral near-rings, where each component is either an Anshel-Clay near-ring or a trivial integral near-ring. We also show

When Are Graded Rings Graded S-Noetherian Rings

open access: yesMathematics, 2020
Let Γ be a commutative monoid, R=⨁α∈ΓRα a Γ-graded ring and S a multiplicative subset of R0. We define R to be a graded S-Noetherian ring if every homogeneous ideal of R is S-finite. In this paper, we characterize when the ring R is a graded S-Noetherian

Polyadic Analogs of Direct Product

open access: yesUniverse, 2022
We propose a generalization of the external direct product concept to polyadic algebraic structures which introduces novel properties in two ways: the arity of the product can differ from that of the constituents, and the elements from different ...

Generalized Left Derivations with Identities on Near-Rings

open access: yesمجلة بغداد للعلوم, 2023
In this paper, new concepts which are called: left derivations and generalized left derivations in nearrings have been defined. Furthermore, the commutativity of the 3-prime near-ring which involves some algebraic identities on generalized left ...
