N5 as a Subalgebra of a Principally Ordered Naturally Ordered Regular Semigroup with a Zero Element

Gama Pinto · مجلة جامعة السلطان قابوس للعلوم · 2025 · 10.53539/2414-536x.1404

We start with a basic and technical result: If S is a principally ordered regular semigroup that has a zero element, 0, then 0* is the biggest element (in fact, idempotent) of S. We obtain necessary and sufficient conditions for a principally ordered naturally ordered regular semigroup, S, with a zero element, to have …

Eventually Pointed Principally Ordered Regular Semigroups

Gama Pinto · مجلة جامعة السلطان قابوس للعلوم · 2020 · 10.24200/squjs.vol24iss2pp139-146

An ordered regular semigroup, , is said to be principally ordered if for every there exists . A principally ordered regular semigroup is pointed if for every element, we have . Here we investigate those principally ordered regular semigroups that are eventually pointed in the sense that for all there exists a positive …
