\(\mathcal{I}_2\)-Cauchy double sequences in 2-normed spaces

Abstract: The concept I-Cauchy and I * -Cauchy sequences were studied by Gürdal and Ac . ık in [On I-Cauchy sequences in 2-normed spaces, Math. Inequal. Appl. 11 (2) (2008), [349][350][351][352][353][354]. In this paper, we introduce the notions of I2-Cauchy and I * 2 -Cauchy double sequences, and study their some properties with the property (AP2) in 2-normed spaces.

“…Now we introduce logarithmic summability in IFNS and prove corresponding Tauberian theorems. For some other studies concerning logarithmic summability and convergence methods in fuzzy setting see [14][15][16][17][18][19][20][21][22][23][24][25][26].…”

“…They also examined the concepts I 2 -limit points and I 2 -cluster points in 2-normed spaces. Dündar and Sever [5] introduced the notions of I 2 and I * 2 -Cauchy double sequences, and studied their some properties with (AP2) in 2-normed spaces.…”

“…A double sequence x = (x mn ) in X is said to be I * 2 -Cauchy sequence if there exists a set M ∈ F (I 2 ) (i.e., H = N × N\M ∈ I 2 ) such that for each ε > 0 and for all (m, n), (s, t) ∈ M, x mn − x st , z < ε, for each nonzero z in X, where m, n, s, t > k 0 = k 0 (ε) ∈ N. In this case we write lim m,n,s,t→∞ x mn − x st , z = 0. Now, we begin with quoting the following lemmas due to Sarabadan et al [24] and Dündar, Sever [5] which are needed throughout the paper.…”
