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.

Some Characterizations for Approximate Biflatness of Semigroup Algebras

Journal of Mathematics, 2023
In this paper, we study an approximate biflatness of l1S, where S is a Clifford semigroup. Indeed, we show that a Clifford semigroup algebra l1S is approximately biflat if and only if every maximal subgroup of S is amenable, ES is locally finite, and l1S

On generators, relations and D-simplicity of direct products, Byleen extensions, and other semigroup constructions [PDF]

, 2015
In this thesis we study two different topics, both in the context of semigroup constructions. The first is the investigation of an embedding problem, specifically the problem of whether it is possible to embed any given finitely presentable semigroup ...

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 ...

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 ...

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.

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

Every group is a maximal subgroup of the free idempotent generated semigroup over a band [PDF]

, 2013
Given an arbitrary group G we construct a semigroup of idempotents (band) BG with the property that the free idempotent generated semigroup over BG has a maximal subgroup isomorphic to G. If G is finitely presented then BG is finite. This answers several
