Ordered semigroup
WebMay 18, 2006 · Abstract. Exactly as in semigroups, Green's relations play an important role in the theory of ordered semigroups—especially for decompositions of such semigroups. WebA partially ordered semigroup (or a po-semigroup for short) is a structure A =(A,≤,⋅)where ≤is a partial order and ⋅is a binary operation that is associative and order-preserving in both variables. If x⋅y≤xand y⋅x≤ xfor all x,y∈A, then A is called two-sided (or negative [5]). A partially ordered monoid (or a po-monoid for short)

Websemigroup and determine which faces of the polyhedra contain these semigroups. We do this by studying the Ap´ery sets of different symmetric numerical semigroups and using partially ordered sets to represent their Ap´ery sets. This paper begins with the necessary background information needed to understand WebIt is known that a fuzzy set of an ordered semigroup is a fuzzy filter if and only its complement is a fuzzy prime ideal. As a generalization of the latter result, it is proved that a fuzzy set of an ordered semigroup is a fuzzy ( m, n) -filter if and only if its complement is a prime generalized fuzzy ( m, n) -ideal.

An algebraic system (S,·,≤) is called a partially ordered semigroup (po-semigroup) if it satisfies (c 1) S is a semigroup with respect to “·”, (c 2) S is a po-set with respect to “≤”, (c 3) If y 1 ≤ y 2 ay 1 ≤ ay 2 ... Websemigroup on Lp(Rd) are order bounded (as discussed in Example 2.5(a)) it follows that all orbits of S are order bounded in Lp(Ω) over the time interval [0,1].
