Interval-valued semiprime fuzzy ideals of semigroups.
Summary: We introduce the notion of (i-v) semiprime (irreducible) fuzzy ideals of semigroups and investigate their different algebraic properties. We study the interrelation among (i-v) prime fuzzy ideals, (i-v) semiprime fuzzy ideals, and (i-v) irreducible fuzzy ideals and characterize regular semigroups by using these (i-v) fuzzy ideals.
