On a New Space of Double Sequences [PDF]

Journal of Function Spaces and Applications, 2013
We introduce a new space of double sequences related to -absolute convergent double sequence space, combining an Orlicz function and an infinity double matrix. We study some properties of and obtain some inclusion relations involving .

On the relation between mixed Morrey spaces and mixed Morrey double-sequence spaces [PDF]

ITM Web of Conferences
In this article, we prove that mixed Morrey double-sequence spaces can be realized as a subspace of mixed Morrey spaces. Our proof extends a similar result for discrete Morrey spaces, obtained by Kikianty and Schwanke in 2019.

Matrix transformations of double convergent sequences with powers [PDF]

Proceedings of the Estonian Academy of Sciences
In 1967, I. J. Maddox generalized the spaces c0, c, ℓ∞ by adding the powers pk (k ∈ ℕ) in the definitions of the spaces to the terms of elements of sequences (xk). Gökhan and Çolak in 2004–2006 defined the corresponding double sequence spaces

On some double Cesàro sequence spaces

Filomat, 2014
In this study, we define the double Ces?ro sequence spaces Cesp, Cesbp and Cesbp0 and examine some properties of those sequence spaces. Furthermore, we determine the ?(bp)-duals of the spaces Cesbp and Cesp.

On Ideal Convergent Difference Double Sequence Spaces in Intuitionistic Fuzzy Normed Linear Spaces

Universal Journal of Mathematics and Applications, 2021
In this paper, we introduce difference double sequence spaces ${I_{2} }^{(\mu,\upsilon)}(M,\Delta)$ and ${I_{2}^{0}}^{(\mu,\upsilon)}(M,\Delta)$ in the intuitionistic fuzzy normed linear spaces.

On the double lacunary (A, φ)-sequence spaces of order α [PDF]

AIP Conference Proceedings, 2019
In this paper, our goal is to extend a few results known in the literature for ordinary (single) sequences to multiply sequences of real numbers. Further we introduce an idea of double lacunary strong (A, φ)- convergence with respect to a modulus function.

A Study on(λ−µ)Zweier Sequences and Their Behaviour in Neutrosophic Normed Spaces [PDF]

Neutrosophic Sets and Systems
Ideal convergence of sequences in neutrosophic normed spaces is defined by ¨Omer Ki¸si [12]. This paper defines new sequence spaces using the Zweier matrix and neutrosophic norm.

On Some Classes of Double Difference Sequences of Interval Numbers

Abstract and Applied Analysis, 2014
The aim of this paper is to introduce some interval valued double difference sequence spaces by means of Musielak-Orlicz function M=(Mij). We also determine some topological properties and inclusion relations between these double difference sequence ...
