Soft ordered semigroups

Mathematical Logic Quarterly, 2010
AbstractMolodtsov introduced 1999 the concept of soft set as a new mathematical tool for dealing with uncertainties that is free from the difficulties that have troubled the usual theoretical approaches. In this paper we apply the notion of soft sets by Molodtsov to ordered semigroups.

OnP-Q ordered semigroups

Periodica Mathematica Hungarica, 1994
A partially ordered semigroup \(S\) is called P-ordered if for any \(a,b \in S\), \(ab \geq b\). The semigroup \(S\) is called Q-ordered if \(a \leq b\) implies \(a = b\) or \(b = ac\) for some \(c \in S\). These are the duals of N- M-ordered semigroups [in \textit{S. Y. Kwan} and \textit{K. P. Shum}, Semigroup Forum 19, 151-175 (1980; Zbl 0438.06010)].
