Intutionistic Fuzzy δ-Continuity and (λ₁, λ₂) – near Compactness in Intutionistic Fuzzy Topological Spaces

The concept of a fuzzy δ-continuity in fuzzy topological spaces was introduced by Soha [20] and (Allam and Zahran [1]). In [14, 16, 18] the notion of nearly compactness has been introduced. In this paper, we introduce the notion of fuzzy δ-continuity in intutionistic fuzzy topological spaces (IFTS's, for short) and give a characterization of such notion. Also, we introduce the notion of (λ₁, λ₂)-near compact which depends on the notion of (λ₁, λ₂)-shading. Finally, we investigate the image of (λ₁, λ₂)-nearly compact spaces under some types of continuous functions.
