Nil-extensions of simple and right -inverse ordered semigroups
A. Jamadar
An ordered semigroup is right -inverse if it is -inverse but not conversely. So the question arises under what condition the converse holds. In this paper we study nil-ex…
On right -inverse ordered semigroups
A. Jamadar
Here we introduce the notion of (left, right) --simple, right -inverse ordered semigroups and discuss characterizations and relationships concerning them. Semilattice deco…
On inverse ordered semigroups
A. Jamadar, K. Hansda
The purpose of this paper is to study the generalization of inverse semigroups (without order). An ordered semigroup S is called an inverse ordered semigroup if for every a 2 S, an…
On inverse and right inverse ordered semigroups
A. Jamadar, K. Hansda
A regular ordered semigroup is called right inverse if every principal left ideal of is generated by an -unique ordered idempotent. Here we explore the theory…
