New double sequence spaces of fuzzy numbers

Quaestiones Mathematicae, 2010
In this paper we introduce some new double sequence spaces of fuzzy numbers using Orlicz function and also we examine that if a sequence of fuzzy numbers is double strongly convergent with respect to an Orlicz function then it is double statistical convergent.

On some modular spaces of double sequences. II

1992
Summary: Let \((\Phi_ i)\) and \((\varphi_ j)\) be two sequences of \(\varphi\)- functions and let \(\Psi\) be a nonnegative, nondecreasing function of \(u\geq 0\) such that \(\Psi(u)\to 0\) as \(u\to 0+\). For a given sequence \(x=(t_{\mu\nu})\in X\), first we introduce \(\varphi_ j\)-modulus and \(\Phi_ i\)-variation.

Inclusion theorems for double lacunary sequence spaces

2005
\textit{A. R. Freedman, J. J. Sember} and \textit{M. Raphael} [Proc. Lond. Math. Soc., III. Ser. 37, 508--520 (1978; Zbl 0424.40008)] introduced a definition of lacunary convergent sequences in Pringsheim sense and studied some Cesàro-type summability spaces related to these notions.
