Linear inequations with 5-digit and regularity conditions on ordered ternary semigroups [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 We investigate linear inequations with 5-digit of regular elements of ordered ternary semigroups, define the notions of ordered weakly left ideals, ordered weakly right ideals and ordered strong bi-ideals of ordered ternary semigroups, give some ...

Semilattice of bisimple regular semigroups [PDF]
Proceedings of the American Mathematical Society, 1971 The main purpose of this paper is to show that a regular semigroup S S is a semilattice of bisimple semigroups if and only if it is a band of bisimple semigroups and that this holds if and only if D \mathcal {D} is a congruence on S S . It is also shown that a quasiregular semigroup

On epimorphisms and structurally regular semigroups [PDF]
Categories and General Algebraic Structures with Applications, 2021 In this paper we study epimorphisms, dominions and related properties for some classes of structurally (n,m)-regular semigroups for any pair (n,m) of positive integers. In Section 2, after a brief introduction of these semigroups, we prove that the class

Quasi-abelian and quasi-solvable regular semigroups
Le Matematiche, 1996 In this note quasi-abelian semigroups are studied and it is proved that they form an e-variety of orthodox semigroups. More, quasi-abelian regular Bruck-Reilly monoids are characterized as extensions of monoids which are (reverse) semidirect products of ...

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

New Types of Fuzzy Interior Ideals of Ordered Semigroups Based on Fuzzy Points [PDF]
Matrix Science Mathematic, 2017 Subscribing to the Zadeh’s idea on fuzzy sets, many researchers strive to identify the key attributes of these sets for new finding in mathematics. In this perspective, new types of fuzzy interior ideals called (∈, ∈ ∨qk)-fuzzy interior ideals of ordered

Epimorphisms, Dominions, and Various Classes of Saturated Semigroups
Journal of Mathematics, 2022 In this paper, we discussed some saturated classes of ℋ-commutative semigroups, left (right) regular semigroups, medial semigroups, and paramedial semigroups. The results of this paper significantly extend the long standing result about normal bands that

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
