Positive implicative ordered filters of implicative semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 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.

Lattice ordered semigroups andΓ-hypersemigroups

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2019
Summary: This paper shows that many results on hypersemigroups do not need any proof as they can be obtained from lattice ordered semigroups.

Monotone iterative technique for nonlocal fractional differential equations with finite delay in Banach space

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, we extend a monotone iterative technique for nonlocal fractional differential equations with finite delay in an ordered Banach space. By using the monotone iterative technique, theory of fractional calculus, semigroup theory and measure of

Semigroups, rings, and Markov chains

open access: yes, 1999
We analyze random walks on a class of semigroups called ``left-regular bands''. These walks include the hyperplane chamber walks of Bidigare, Hanlon, and Rockmore.

$\pi$-inverse ordered semigroups

open access: yesDiscussiones Mathematicae - General Algebra and Applications
Summary: This article deals with the generalization of \(\pi\)-inverse semigroups without order to ordered semigroups. Here we characterize \(\pi\)-inverse ordered semigroups by their ordered idempotents and bi-ideals.

Left strongly archimedean ordered semigroups

open access: yesSemigroup Forum, 2014
As we know, a semigroup (without order) is left strongly Archimedean if and only if it is a nil extension of a left strongly simple semigroup [\textit{M. S. Mitrović}, Semilattices of Archimedean semigroups. Niš: University of Niš, Faculty of Mechanical Engineering (2003; Zbl 1086.20033)]. It is interesting to know what is the matter in case of ordered

m-Ordered semigroups

open access: yesDiscussiones Mathematicae - General Algebra and Applications
In this paper we define and study m-ordered semigroups. In particular, idempotents and subsemigroups of m-ordered semigroups are studied and is established a characterization of inverse semigroups that, under natural order, are m-ordered semigroups.

On Epiorthodox Semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
It has been well known that the band of idempotents of a naturally ordered orthodox semigroup satisfying the “strong Dubreil-Jacotin condition” forms a normal band.
