A further study on ordered regular equivalence relations in ordered semihypergroups

open access: yesOpen 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.

Semigroups Characterized by Their Generalized Fuzzy Ideals

open access: yesJournal of Mathematics, 2013
We have characterized right weakly regular semigroups by the properties of their (∈,∈∨qk)-fuzzy ideals.

Regularity of Po-Γ-semigroups in Terms of Fuzzy Subsemigroups and Fuzzy Bi-ideals

open access: yesFuzzy 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-

A structure theorem for completely regular semigroups

open access: yes, 1987
Structure theorems for arbitrary completely regular semigroups have been given by Yamada, Warne, Petrich, and Clifford. A new structure theorem for these semigroups is proved here.

Semigroups with inverse skeletons and Zappa-Sz'{e}p products [PDF]

open access: yesCategories 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'

REGULAR SEMIGROUPS WITH NORMAL IDEMPOTENTS

open access: yes, 2017
In this paper, we investigate regular semigroups that possess a normal idempotent. First, we construct a nonorthodox nonidempotent-generated regular semigroup which has a normal idempotent.
