Bipolar Valued Fuzzy d-Ideals of d-algebra

Abstract

In this paper we introduce and study the concept of bipolar fuzzy dideal of dalgebra and we characterize bipolar fuzzy dideal to the crisp dideal Further we prove that every bipolar fuzzy dideal is a bipolar fuzzy subalgebra and converse need not be Also we prove that the homomorphic image and inverse image of a bipolar fuzzy dideal is a bipolar fuzzy dideal
