Interval Valued Q-fuzzy Quasi-ideals in a Semigroups

Abstract

We initiate the study of interval-valued Q-fuzzy qu asi-ideal of a semigroup. In Section 2, we list some basic definitions in the la t r sections. In Section 3, we investigate interval-valued Q-fuzzy subsemigroups and in Sectio n 4, we define interval valued Q-fuzzy quasi-ideals and establish some of their ba sic properties.
