Ordered semigroup

In mathematics, an ordered semigroup is a semigroup (S,•) together with a partial order ≤ that is compatible with the semigroup operation, meaning that x ≤ y implies z•x ≤ z•y and x•z ≤ y•z for all x, y, z in S. An ordered monoid and an ordered group are, respectively, a monoid or a group that are endowed with a partial order that makes them ordered semigroups. The terms posemigroup, pogroup and … WebProposition 2 has a kind of (trivial) converse: Every linearly orderable semigroup is torsion-free and cancellative (indeed, something stronger can be proved; i.e., none of the elements of the semigroup has finite order unless the semigroup is unital and …

WebJul 1, 2024 · Let's say an ordered semigroup S is comparable with identity if it can be embedded into an ordered monoid S 1 in which every element is comparable with 1, and the order of S is a subset of the order of S 1. Clearly, any totally ordered monoid is a semigroup comparable with 1.

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].
