A NOTE ON ORDERED QUASI--IDEALS IN INTRA-REGULAR PO--SEMIGROUPS
Abul Basar · 2015
In this paper, we characterize intra-regular po--semigro ups through ordered quasi--ideals, ordered right -ideals and ordere d left -ideals. Also, we investigate the po--semigroup in which the regular and i ntra-regular sub-- semigroups are idempotents, left regular idempotents, commutative and idem- potents.
