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)].

Normally Ordered Inverse Semigroups
Semigroup Forum, 1998Let \(S\) be an inverse semigroup and \(E\) the set of its idempotents. Suppose that there exists a partial order \(\ll\) on \(E\) such that two idempotents are \(\ll\)-comparable if and only if they belong to the same \(\mathcal J\)-class of \(S\) and, for all \(s\in S\) and \(e,f\in Ess^{-1}\), \(e\ll f\) implies \(s^{-1}es\ll s^{-1}fs\).

Bisimple Inverse Semigroups as Semigroups of Ordered Triples
Canadian Journal of Mathematics, 1968In (8) and (13) it has been shown that certain bisimple inverse semigroups, called bisimple ω-semigroups and bisimple Z-semigroups, can be represented as semigroups of ordered triples. In these cases, two of the components of each triple are integers, and the third is drawn from a fixed group.

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.
