Interval-Valued Semiprime Fuzzy Ideals of Semigroups
Advances in Fuzzy Systems, 2014 We introduce the notion of (i-v) semiprime (irreducible) fuzzy ideals of semigroups and investigate its different algebraic properties. We study the interrelation among (i-v) prime fuzzy ideals, (i-v) semiprime fuzzy ideals, and (i-v) irreducible fuzzy ...

, 1981 SynopsisA regular semigroup S is called V-regular if for any elements a, b ∈ S and any inverse (ab)′ of ab, there exists an inverse a′ of a and an inverse b′ of b such that (ab)′ = b′a′.

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 ...

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.

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 Weakly Regular Fuzzy Ordered Ternary Semigroups [PDF]
, 2016 Weakly regular ordered ternary semigroups are characterized in terms of fuzzy left, fuzzy right, fuzzy quasi-ideals and fuzzy bi-ideals, which generalizes and unifies results on weakly regular ordered semigroups and weakly regular ternary ...
