Abstract
Our goal in this work is to introduce the notion V , λ ( I ) 2 -summability and ideal λ-double statistical convergence of order α with respect to the intuitionistic fuzzy norm μ , v . We also make some observations about these spaces and prove some inclusion relations.
Highlights
Intuitionistic fuzzy set (IFNS) is one of the generalizations of fuzzy set theory [1]
IFNS is characterized by a membership function and a non-membership function such that the sum of both values is less than one
We intend to use ideals to introduce the concept of Iλ-double statistical convergence of order α with respect to the intuitionistic fuzzy normed space (μ, v), and study some of its consequences
Summary
Intuitionistic fuzzy set (IFNS) is one of the generalizations of fuzzy set theory [1]. In [26] Mohiuddine and Lohani introduced the notion of the generalized statistical convergence in intuitionistic fuzzy normed spaces. We intend to use ideals to introduce the concept of Iλ-double statistical convergence of order α with respect to the intuitionistic fuzzy normed space (μ, v), and study some of its consequences. Using the continuous t-norm and t-conorm, Saadati and Park [4] has recently introduced the concept of intuitionistic fuzzy normed space as follows. The five-tuple (X, μ, v, ∗, ♦) is said to be an intuitionistic fuzzy normed space (for short, IFNS) if X is a vector space, ∗ is a continuous t-norm, ♦ is a continuous t-conorm, and μ, v are fuzzy sets on X × (0, ∞) satisfying the following conditions for every x, y ∈ X, and s, t > 0 [4]: Math.
