Semigroups Characterized by Their Generalized Fuzzy Ideals
Journal of Mathematics, 2013 We have characterized right weakly regular semigroups by the properties of their (∈,∈∨qk)-fuzzy ideals.

A further study on ordered regular equivalence relations in ordered semihypergroups
Open Mathematics, 2018 In this paper, we study the ordered regular equivalence relations on ordered semihypergroups in detail. To begin with, we introduce the concept of weak pseudoorders on an ordered semihypergroup, and investigate several related properties.

Regularity of Po-Γ-semigroups in Terms of Fuzzy Subsemigroups and Fuzzy Bi-ideals
Fuzzy Information and Engineering, 2015 In this paper, the notions of fuzzy subsemigroups and fuzzy bi-ideals of a po-Γ-semigroup are introduced with some of their important properties investigated. We obtain some characterizations of regular, intra-regular po-Γ-semigroups in terms of fuzzy bi-

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

Semigroups with inverse skeletons and Zappa-Sz'{e}p products [PDF]
Categories and General Algebraic Structures with Applications, 2013 The aim of this paper is to study semigroups possessing $E$-regular elements, where an element $a$ of a semigroup $S$ is {em $E$-regular} if $a$ has an inverse $a^circ$ such that $aa^circ,a^circ a$ lie in $ Esubseteq E(S)$. Where $S$ possesses `enough'

On Intra-regular Ordered Semigroups
Semigroup Forum, 1998 An ordered semigroup \(S\) is intra-regular if and only if it is a semilattice of simple semigroups, equivalently, if \(S\) is a union of simple subsemigroups of \(S\) [\textit{N. Kehayopulu}, Semigroup Forum 46, 271-278 (1993; Zbl 0776.06013)]. A \(poe\)-semigroup \(S\) is a semilattice of simple semigroups if and only if it is a semilattice of simple

A common framework for restriction semigroups and regular ∗ -semigroups
Journal of Pure and Applied Algebra, 2012 Let \(S\) be a regular \(*\)-semigroup, that is, a semigroup with involution \(a\mapsto a^{-1}\) for which \(a^{-1}\) is an inverse of \(a\). Let \(E_S\) denote the set of idempotents of \(S\) and \(P_S\) the set of \textit{projections} of \(S\), that is, \(P_S=\{e\in E_S:e=e^{-1}\}\).
