A New Characterization of Intra-regular Semi-groups
Xie Xiang-yun · Journal of Wuyi University · 2011
The concept of intraval valued fuzzy sets on intra-regular semigroups is introduced.Moreover,the operations with interval valued fuzzy sets are discussed.Finally,some theorems are given to characterize intra-regular semigroups in terms of interval valued fuzzy left(resp.right,bi-) ideals of semigroups.
