P A ON (m, n)-IDEALS OF AN ORDERED SEMIGROUP

open access: yes, 2015
: In this paper we introduce the concept of (m, n)-simple ordered semigroups extending the notion of simple ordered semigroups, and prove that an ordered semigroup (S, ·, ≤) does not contain proper (m, n)-ideals if and only if it is both (m, 0)-simple ...

The hull-kernel topology on prime ideals in ordered semigroups

open access: yesOpen Mathematics
The aim of this study is to develop the theory of prime ideals in ordered semigroups. First, to ensure the existence of prime ideals, we study a class of ordered semigroups which will be denoted by SIP{{\mathbb{S}}}_{IP}.

HOMOTHETIC INTERVAL ORDERS

open access: yes, 2008
We give a characterization of the non-empty binary relations  on a N∗-set A such that there exist two morphisms of N∗-sets u1, u2: A → R+ verifying u1 ≤ u2 and x  y ⇔ u1(x)>u2(y). They are called homothetic interval orders.

The characterization of Nelson algebras by Sheffer stroke

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this study, Sheffer stroke Nelson algebras (briefly, s-Nelson algebras), (ultra) ideals, quasi-subalgebras, quotient sets, and fuzzy structures on these algebraic structures are introduced.
