Ordered Vector Valued Double Sequence Spaces

open access: bronzeFasciculi Mathematici, 2015
AbstractIn this paper we have introduced an order relation on convergent double sequences and have constructed an ordered vector space, Riesz space, order complete vector space in case of double sequences. We have verified the Archimedean property.

On almost B-summable double sequence spaces [PDF]

open access: yesJournal of Inequalities and Applications, 2018
The concept of a four-dimensional generalized difference matrix and its domain on some double sequence spaces was recently introduced and studied by Tuğ and Başar (AIP Conference Proceedings, vol. 1759, 2016) and Tuğ (J. Inequal. Appl. 2017(1):149, 2017).

On a New Space of Double Sequences [PDF]

open access: yesJournal 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 .

Double lacunary sequence spaces of double interval numbers [PDF]

open access: diamondProyecciones (Antofagasta), 2012
In this paper we introduce the concepts of double lacunary strongly convergence and double lacunary statistical convergence of double interval numbers. We prove some inclusion relations and study some of their properties.

Webbed spaces, double sequences, and the Macke convergence condition [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 1999
In [3], Gilsdorf proved, for locally convex spaces, that every sequentially webbed space satisfies the Mackey convergence condition. In the more general frame of topological vector spaces, this theorem and its inverse are studied. The techniques used are double sequences and the localization theorem for webbed spaces.

On the New Double Binomial Sequence Space

open access: diamondTurkish Journal of Mathematics and Computer Science, 2020
The aim of this paper is to present the new double Binomial sequence space $\mathcal{B}_{p}^{r,s}$ which consists of all sequences whose double Binomial transforms of orders $r,s$ ($r$ and $s$ are nonzero real numbers with $r+s \neq 0$) are in the space $\mathcal{L}_p$, where $0<p<\infty$.

On Zweier I-convergent double sequence spaces

open access: hybridFilomat, 2016
In this article we introduce the Zweier I-convergent double sequence spaces 2ZI, 2ZI0 and 2ZI1. We prove the decomposition theorem and study topological properties, algebraic properties and some inclusion relations on these spaces.

A Study on Statistical Convergence of Triple Sequences in Intuitionistic Fuzzy Normed Space [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
S. Karkaus, K. Demirci, and O. Duman in 2008 studied the statistical convergence of a single sequence over Intuitionistic fuzzy normed space(\textbf{IFNS}). M. Mursaleen in 2009, generalized the above work for double sequences over IFNS.
