(m, n)-Ideals in Semigroups Based on Int-Soft Sets

Journal of Mathematics, 2021
Algebraic structures play a prominent role in mathematics with wide ranging applications in many disciplines such as theoretical physics, computer sciences, control engineering, information sciences, coding theory, and topological spaces.

RIGHT PURE UNI-SOFT IDEALS OF ORDERED SEMIGROUPS [PDF]

Matrix Science Mathematic, 2018
In this paper, we initiate the study of pure uni-soft ideals in ordered semigroups. The soft version of right pure ideals in ordered semigroups is considered which is an extension of the concept of right pure ideal in ordered semigroups. We also give the

Fermatean fuzzy semi-prime ideals of ordered semigroups

Topological Algebra and its Applications, 2023
Fermatean fuzzy sets (FFSs) are invented to resolve the underlying limitations of intuitionistic fuzzy sets and Pythagorean fuzzy sets. The major goal of this study is to introduce Fermatean fuzzy semi-prime ideals of ordered semigroups.

On Vn-semigroups

Open Mathematics, 2015
In this paper, we give some new characterizations of orthodox semigroups in terms of the set of inverses of idempotents. As a generalization, a new class of regular semigroups, namely Vn-semigroups, is introduced.

Ordered semigroups characterized by (ϵ ϵ vqk)-fuzzy generalized bi-ideals [PDF]

, 2012
In this paper, we introduce a considerable machinery that permits us to characterize a number of special (fuzzy) subsets in ordered semigroups. In this regard, we generalize (Davvaz and Khan in Inform Sci 181:1759-1770 2011) and define (is an element of,

F-regular semigroups

Journal of Algebra, 2004
A regular semigroup \(S\) is called \(F\)-regular if there exists a group congruence \(\rho\) on \(S\) such that every \(\rho\)-class contains a greatest element with respect to the natural partial order on \(S\). Continuing many investigations of \(F\)-regular semigroups, the authors characterize them and give a new representation of such semigroups ...

Neutrosophic ℵ −bi-ideals in semigroups [PDF]

Neutrosophic Sets and Systems, 2020
In this paper, we introduce the notion of neutrosophic ℵ-bi-ideal for a semigroup. We infer different semigroups using neutrosophic ℵ -bi-ideal structures.

The algebra of adjacency patterns: Rees matrix semigroups with reversion [PDF]

, 2009
We establish a surprisingly close relationship between universal Horn classes of directed graphs and varieties generated by so-called adjacency semigroups which are Rees matrix semigroups over the trivial group with the unary operation of reversion.

Proper Regular Semigroups [PDF]

Proceedings of the American Mathematical Society, 1978
In a recent paper, D. B. McAlister gave several characterizations of proper inverse semigroups. In this paper, the concept of proper is extended to the class of regular semigroups. This is done by requiring that the set of idempotents of the semigroup coincides with the kernel of the minimum group congruence on the semigroup.
