On Certain Proximities and Preorderings on the Transposition Hypergroups of Linear First-Order Partial Differential Operators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
The contribution aims to create hypergroups of linear first-order partial differential operators with proximities, one of which creates a tolerance semigroup on the power set of the mentioned differential operators.

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 (
