A left identity of a semigroup (or more generally, magma) is an element such that for all in , . Similarly, a right identity is an element such that for all in , . Left and right identities are both called one-sided identities. A semigroup may have one or more left identities but no right identity, and vice versa. A two-sided identity (or just identity) is an element that is both a left and right identity. Semigroups with a two-sided identity are called monoids. A semigroup may have at most one tw… WebFeb 9, 2012 · DEFINITION 3.71 : An ordered -semigroup S is said to be a cyclic ordered -semigroup if S is a cyclic ordered -subsemigroup of S itself.

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) Web1. Introduction. In this paper order will always mean linear or total order, and, unless otherwise stated, the composition of any semigroup will be denoted by +.
