In this paper, we study the concepts of Wijsman statistical convergence, Wijsman lacunary statistical convergence, Wijsman lacunary convergence and Wijsman strongly lacunary convergence double sequences of sets and investigate ...

In this study, we determine the fine spectrum of the matrix operator ∆+ defined by an upper triangle double band matrix acting on the sequence space c_0 with respect to the Goldberg’s classification. As a new development, ...

In this paper, we investigate multipliers for bounded convergence of double sequences and study some properties and relations between l2 ∞, c2(b) and c20(b).

In this paper, the concept of asymptotically lacunary I_2-invariant equivalence, the concepts of asymptotically lacunary σ_2-equivalence and the concept of asymptotically lacunary invariant S_2-equivalence for double ...

In this study, we examinate the ideas of Wijsman strongly lacunary Cauchy, Wijsman strongly I-lacunary Cauchy and Wijsman strongly I∗-lacunary Cauchy sequences of sets and investigate the relationship between them.

In this paper, we introduce the notions of ( I_2, I), ( I^∗2 ,I^∗)-convergence and ( I_2, I), ( I^∗2, I^∗) Cauchy double sequence in regular sense in 2-normed spaces. Also, we study some properties of these concepts.

In this work, using the concept of I-convergence and using the concept of rough convergence, we introduced the notion of rough I-convergence and the set of rough I-limit points of a sequence and obtained two rough I-convergence ...

In this study, we have investigated the concepts of lacunary summable, lacunary statistical convergence and lacunary statistically Cauchy sequence for double sequences in fuzzy normed spaces. Also, we have investigated ...

In this paper, we introduce the notions of regularly (IW2,IW) -convergence, regularly (IW2*,IW*) -convergence, regularly (IW2,IW) -Cauchy and regularly (IW2*,IW*) -Cauchy double sequence of sets and investigate the ...
