Ideal convergence in 2-fuzzy 2-normed spaces

Yıl 2017, Cilt: 46 Sayı: 1, 149 - 162, 01.02.2017

Öz

In this paper we introduce the notion of $\mathcal{I}$-convergence and $\mathcal{I}$-Cauchyness of sequences in 2-fuzzy 2-normed spaces and established some basic results related to these notions. Further, we define $\mathcal{I}$-limit and $\mathcal{I}$-cluster points of a sequence in a 2-fuzzy 2-normed linear space and investigate the relations between these concepts.
