Ordered semigroup
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) WebAn ordered semigroup is a semigroup S equipped with a stable order relation on S. Ordered monoids are de ned analogously. The notation (S; ) will sometimes be used to emphasize the role of the order relation, but most of the time the order will be implicit and the notation Swill be used for semigroups as well as for ordered semigroups.
