Ordered Semigroups Based on ∈,∈∨qkδ-Fuzzy Ideals

Advances in Fuzzy Systems, 2018
A new trend of using fuzzy algebraic structures in various applied sciences is becoming a central focus due to the accuracy and nondecoding nature. The aim of the present paper is to develop a new type of fuzzy subsystem of an ordered semigroup S.

New approach towards different ideals using bipolar valued intuitionistic neutrosophic set of an ordered semigroups [PDF]

Neutrosophic Sets and Systems
This paper introduces the notion of bipolar valued intuitionistic neutrosophic subsemigroup (BIntNS), bipolar valued intuitionistic neutrosophic left ideal (BIntNLI), bipolar valued intuitionistic neutrosophic right ideal (BIntNRI), bipolar valued ...

NORMALLY ORDERED SEMIGROUPS [PDF]

Glasgow Mathematical Journal, 2008
AbstractIn this paper we introduce the notion of normally ordered block-group as a natural extension of the notion of normally ordered inverse semigroup considered previously by the author. We prove that the classNOSof all normally ordered block-groups forms a pseudovariety of semigroups and, by using the Munn representation of a block-group, we deduce

A Study of Ordered Ag-Groupoids in terms of Semilattices via Smallest (Fuzzy) Ideals

Advances in Fuzzy Systems, 2018
An ordered AG-groupoid can be referred to as an ordered left almost semigroup, as the main difference between an ordered semigroup and an ordered AG-groupoid is the switching of an associative law.

Pseudoorder in ordered semigroups

Semigroup Forum, 1995
The notion of pseudoorder on a partially ordered (p.o.) semigroup \((S, \cdot, \leq)\) was introduced by the authors in an earlier paper [ibid. 50, No. 2, 161-177 (1995; Zbl 0823.06010)]. A transitive, left- and right- compatible relation \(\rho\) on \(S\) is a pseudoorder if \(a \leq b\) implies \(a \rho b\) (consequently, \(\rho\) is reflexive ...

Generalized Bi-ideal of Ordered Semigroup Related to Intuitionistic Fuzzy Point [PDF]

Matrix Science Mathematic, 2017
Intuitionistic fuzzy generalized bi-ideals play an important role in the study of ordered semigroups. In this paper, we try obtain more general form of intuitionistic fuzzy generalized bi-ideal of an ordered semigroup.

On (∈, ∈ ∨q)−anti fuzzy bi-ideals of ordered semigroup [PDF]

Journal of Hyperstructures, 2012
In this paper, we introduce the notions of (∈¯, ∈ ∨ ¯q¯)−fuzzy bi-ideals, (∈, ∈ ∨q)−antifuzzy bi-ideals and (∈¯, ∈ ∨ ¯q¯)−antifuzzy bi-ideals of an ordered semigroup.

Some ordered hypersemigroups which enter their properties into their σ-classes [PDF]

Journal of Hyperstructures, 2017
An important problem in the theory of ordered hypersemigroups is to describe the ordered hypersemigroups which enter their properties into their σ-classes.
