The characterization of regular ordered semigroups by ( , )     q fuzzy ideals

FengLian Yuan, QuanFu Lou and XiaoYing Sun

In this paper, based on the inclusion and quasi-coincident relation of fuzzy sets, we introduce and investigate the concepts of ( , )     q fuzzy quasi-ideals and interior ideals. Also, the characterization of regular ordered semigroups in terms of ( , )     q fuzzy left ideals (right ideals, bi-ideals, quasi-ideals, interior ideals) is also studied.
