Domain theory and mirror properties in inverse semigroups [PDF]

open access: yes, 2012
Inverse semigroups are a class of semigroups whose structure induces a compatible partial order. This partial order is examined so as to establish mirror properties between an inverse semigroup and the semilattice of its idempotent elements, such as ...

Positive implicative ordered filters of implicative semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 12, Page 801-806, 2000., 2000
We introduce the notion of positive implicative ordered filters in implicative semigroups. We show that every positive implicative ordered filter is both an ordered filter and an implicative ordered filter. We give examples that an ordered filter (an implicative ordered filter) may not be a positive implicative ordered filter.

A characterization of translational hulls of a strongly right type B semigroup

open access: yesOpen Mathematics, 2019
The aim of this paper is to study the translational hull of a strongly right type B semigroup. Our main result is to prove that the translational hull of a strongly right type B semigroup is itself a strongly right type B semigroup. As an application, we

p‐systems in local Noether lattices

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 4, Page 655-660, 1994., 1993
In this paper we introduce the concept of a p‐system in a local Noether lattice and obtain several characterizations of these elements. We first obtain a topological characterization and then a characterization in terms of the existence of a certain type of decreasing sequence of elements.

Some characterizations of equivalence relation on contraction mappings

open access: yesScientific African, 2020
Let Tn be the set of full transformations and Pn be the set of partial transformations. It is shown that Tn form a semi-group of order nn and Pn form a semi-group of order(n+1)n. Let ρ(n,m) be a binary relation then we define the image set of ρ(n,m), I(ρ)

MONOIDS OF S-H FUZZY PARTITIONS OF A SET

open access: yes, 2015
This research note constructs S-H fuzzy collections and S-H fuzzy partitions of a finite set. The main objective of the paper lies in defining two different operations on a class of S-H fuzzy partitions of a set and, in turn, proving that these give rise

Singly generated quasivarieties and residuated structures [PDF]

open access: yes, 2019
A quasivariety K of algebras has the joint embedding property (JEP) iff it is generated by a single algebra A. It is structurally complete iff the free countably generated algebra in K can serve as A.

Filters of strong Sheffer stroke non-associative MV-algebras

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
In this paper, at first we study strong Sheffer stroke NMV-algebra. For getting more results and some classification, the notions of filters and subalgebras are introduced and studied.

ON BASES AND MAXIMAL IDEALS IN AN ORDERED SEMIGROUP

open access: yes, 2014
In this paper the concepts of left base, right base and two-sided base of an ordered semigroup are introduced. A sufficient condition for an ordered semigroup contains right bases is given.

Intuitionistic fuzzy interior ideal of semigroup based on intuitionistic fuzzy point [PDF]

open access: yesMatrix Science Mathematic, 2017
The intuitionistic fuzzification of the notion of an interior ideal in ordered semigroups is considered. The purpose of this study is to introduce the notion of (∈, ∈ vq)-intuitionistic fuzzy interior ideals and (∈, ∈)-intuitionistic fuzzy nterior ideals
