An Algebraic Approach to Unital Quantities and their Measurement

open access: yesMeasurement Science Review, 2016
The goals of this paper fall into two closely related areas. First, we develop a formal framework for deterministic unital quantities in which measurement unitization is understood to be a built-in feature of quantities rather than a mere annotation of ...

Ordered Regular Semigroups with Biggest Associates

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
We investigate the class BA of ordered regular semigroups in which each element has a biggest associate x† = max {y | xyx = x}. This class properly contains the class PO of principally ordered regular semigroups (in which there exists x⋆ = max {y | xyx ...

On (m, n)-ideals and (m, n)-regular ordered semigroups [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2016
Let m, n be non-negative integers. A subsemigroup A of an ordered semigroup (S,  ,  is called an (m, n)-ideal of S if (i) Am SAn  A, and (ii) if x  A, y  S such that y  x, then y  A. In this paper, necessary and sufficient conditions for every (
