Abstract

In 1999, Ozbakir and Coker [23] introduced the concept intuitionistic fuzzy multifunctions and studied their lower and upper intuitionistic fuzzy semi continuity from a topological space to an intuitionistic fuzzy topological space. The present paper introduces the concept of α-continuous intuitionistic fuzzy multifunctions. An Intuitionistic fuzzy multifunction F from a topological spaces (X,T) to an intuitionistic fuzzy toplogical spaces (Y,Γ) is said to be Intuitionistic fuzzy α-continuous at a point if for any G ̃_1,G ̃_2∈IFO(Y) such that F(x_0)⊂G ̃_1 and F(x_0)∩G ̃_2 there exists U∈αO(X) containing x_0 such that F(u)⊂G ̃_1 and F(u)∩G ̃_2,∀ u∈U. F is called Intuitionistic fuzzy α-continuous if it has this property at each point of X. Several properties and characterizations of Intuitionistic fuzzy α-continuous
