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.

Partial orders in regular semigroups [PDF]

open access: yesProyecciones (Antofagasta), 2011
First we have obtained equivalent conditions for a regular semigroup and is equivalent to N = N1 It is observed that every regular semigroup is weakly separative and C ⊆ S and on a completely regular semigroup S ⊆  N and S is partial order . It is also obtained that a band (S, .) is normal iff C = N .

On fuzzy points in semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We consider the semigroup S¯ of the fuzzy points of a semigroup S, and discuss the relation between the fuzzy interior ideals and the subsets of S¯ in an (intra-regular) semigroup S.

A formula for jumping numbers in a two-dimensional regular local ring [PDF]

open access: yes, 2018
In this article we give an explicit formula for the jumping numbers of an ideal of finite colenght in a two-dimensional regular local ring with an algebraically closed residue field.

An (α,β)-Hesitant Fuzzy Set Approach to Ideal Theory in Semigroups

open access: yesBulletin of the Section of Logic, 2022
The aim of this manuscript is to introduce the \((\alpha,\beta)\)-hesitant fuzzy set and apply it to semigroups. In this paper, as a generalization of the concept of hesitant fuzzy sets to semigroup theory, the concept of \((\alpha,\beta)\)-hesitant ...

On an equivalence between regular ordered Γ-semigroups and regular ordered semigroups

open access: yesOpen Mathematics, 2020
In this paper, we develop a technique which enables us to obtain several results from the theory of Γ-semigroups as logical implications of their semigroup theoretical analogues.

Adjoint regular rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Let R be a ring. The circle operation is the operation a∘b=a+b−ab, for all a,b∈R. This operation gives rise to a semigroup called the adjoint semigroup or circle semigroup of R. We investigate rings in which the adjoint semigroup is regular. Examples are

Valuation Semigroups of Two Dimensional Local Rings

open access: yes, 2014
We consider the question of when a semigroup is the semigroup of a valuation dominating a two dimensional noetherian local domain, giving some surprising examples.

Bipolar complex fuzzy semigroups

open access: yesAIMS Mathematics, 2023
The notion of the bipolar complex fuzzy set (BCFS) is a fundamental notion to be considered for tackling tricky and intricate information. Here, in this study, we want to expand the notion of BCFS by giving a general algebraic structure for tackling ...

Slice regular semigroups [PDF]

open access: yesTransactions of the American Mathematical Society, 2018
In this paper we introduce the notion of slice regular right linear semigroup in a quaternionic Banach space. It is an operatorial function which is slice regular (a noncommutative counterpart of analyticity) and which satisfies a noncommutative semigroup law characterizing the exponential function in an infinite dimensional noncommutative setting.
