Abstract

In this paper, the concepts of I2 -Cauchy, I2* -Cauchy double sequences in fuzzy n-normed spaces were introduced and some properties and relations of them were studied. We show that if a double sequence (xmr) in X is an I2* -double Cauchy sequence, then it is I2 -double Cauchy sequence, where I2 denotes the ideal of subsets of N×N.

Keywords

Ideal, Double Sequences, Cauchy Sequence, I2 -Convergence.
