A set of axioms which define a positively ordered partial semigroup with identity, an alternative measurement system, is introduced. The positively ordered partial semigroup with identity is defined by a set A of objects, an order among those objects, an

Interior and closure operators on residuated ordered semigroup(剩余序半群的内部和闭包算子)
In this paper, the concept of inner and closure operators on residuated ordered semigroups is introduced, some of their related algebraic properties are studied.

Ordered Regular Semigroups with Biggest Associates
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]
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 (

Hypergroup deformations of semigroups
We view the well-known example of the dual of a countable compact hypergroup, motivated by the orbit space of p-adic integers by Dunkl and Ramirez (Trans Am Math Soc 202:339-356, 1975), as hypergroup deformation of the max semigroup structure on the ...

Completely positive maps of order zero [PDF]
We say a completely positive contractive map between two C<sup>*</sup>-algebras has order zero, if it sends orthogonal elements to orthogonal elements. We prove a structure theorem for such maps. As a consequence, order zero maps are in one-

Filters in ordered $\Gamma$-semigroups
Let \(M\) be an ordered \(\Gamma\)-semigroup. The author considers some relations between the filter \(N(a)\) of \(M\) generated by an element \(a\) of \(M\) and the complete semilattice congruence \(\mathcal N\) on \(M\) defined by \(\{(a,b) \mid N(a)=N(b)\}\). He also gives some examples of ordered \(\Gamma\)-semigroups. For \(\Gamma=\{\gamma\}\) (\(\
