The Hilbert Space of Double Fourier Coefficients for an Abstract Wiener Space
Mathematics, 2021 Fourier series is a well-established subject and widely applied in various fields. However, there is much less work on double Fourier coefficients in relation to spaces of general double sequences.

On paranormed type fuzzy I -convergent double multiplier sequences [PDF]
Kuwait Journal of Science, 2013 In this article, we introduce the classes of fuzzy real valued double sequences and , where is a multiplier sequence of non-zero real numbers and is a double sequence of bounded strictly positive numbers.

Journal of Mathematical Sciences and Modelling, 2019 In this paper, we introduce the concepts of αβ−statistical convergence and strong αβ− summability of double sequences and investigate the relation between these two new concepts. Moreover, statistical convergence and αβ− statistical convergence of double

On I θ 2 $\mathcal{I}_{{\theta}_{2}}$ -convergence in fuzzy normed spaces
Journal of Inequalities and Applications, 2020 In this study, first, lacunary convergence of double sequences is introduced in fuzzy normed spaces, and basic definitions and theorems about lacunary convergence for double sequences are given in fuzzy normed spaces.

Generalized Fermat, double Fermat and Newton sequences [PDF]
, 2003 In this paper, we discuss the relationship among the generalized Fermat, double Fermat, and Newton sequences. In particular, we show that every double Fermat sequence is a generalized Fermat sequence, and the set of generalized Fermat sequences, as well ...

Asymptotically double lacunry equivalent sequences defined by Orlicz functions
Acta Scientiarum: Technology, 2014 This paper presents the following definition which is natural combition of the definition for asymptotically equivalent and Orlicz function. The two nonnegative double sequences x=(x_{k,l}) and y=(y_{k,l}) are said to be M-asymptotically double ...

Double uniform density and corresponding convergence of double sequences [PDF]
, 2012 We introduce the concept of double uniform density of subsets of and the study the corresponding convergence (namely, Iu-convergence) of double sequences. Further we solve an inequality related to the Iu-limit superior of bounded double sequences in line

Lacunary Statistical Convergence in Measure for Double Sequences of Fuzzy Valued Functions
Journal of Mathematics, 2021 Based on the concept of lacunary statistical convergence of sequences of fuzzy numbers, the lacunary statistical convergence, uniformly lacunary statistical convergence, and equi-lacunary statistical convergence of double sequences of fuzzy-valued ...
