On (λ,μ,ζ)-Zweier ideal convergence in intuitionistic fuzzy normed spaces

Abstract

In this paper, we introduce and study a new type of convergence which is namely (?,?,?)-Zweier convergence and (?,?,?)-Zweier ideal convergence of triple sequences x = (xijk) in intuitionistic fuzzy normed spaces (IFNS), where ? = (?n), ? = ((?m) and ?= (?p) are three non-decreasing sequences of positive real numbers such that each tend to infinity. Besides, we define and study (?,?,?)-Zweier Cauchy and (?,?,?)-Zweier ideal Cauchy sequences on the said space and establish some relations among them. problem.
