On difference ideal convergence of double sequences in random 2-normed spaces

icon-email Bipan Hazarika

Abstract

An ideal $I$ is a family of subsets of positive integers $\mathbb{N}$ which is closed under taking finite unions and subsets of its elements. We define and study the notions of $\Delta^{n}$-ideal convergence and $\Delta^{n}$-ideal Cauchy double sequences in random $2$-normed spaces, and prove some interesting theorems.
