Generalized Nörlund and Nörlund-type Means of Sequences of Fuzzy Numbers

Convergence Factors for Double Series Summable by Nörlund Means.

In a note' published in volume 21 of these PROCEEDINGS I gave necessary and sufficient conditions for convergence factors in simply infinite series summable by N6rlund means. The purpose of the present note is to furnish analogous results for double series. We are given a doubly infinite set of complex constants cij (i, j = 0, 1, 2, 3, .. .), where coo 0 0 and Zc,ix'y' is convergent for I x I <...

Some Remarks on Generalized Sequence Space of Bounded Variation of Sequences of Fuzzy Numbers

The idea of difference sequences of real (or complex) numbers was introducedby Ki zmaz cite{Kizmaz}. In this paper, using the difference operator and alacunary sequence, we introduce and examine the class of sequence $bv_{theta}left(  Delta,mathcal{F}right)  .$ We study some of its properties likesolidity, symmetricity, etc.

Nagarajan Subramanian and Ayhan Esi THE NÖRLUND SPACE OF DOUBLE ENTIRE SEQUENCES

Let Γ denote the spaces of all double entire sequences. Let Λ denote the spaces of all double analytic sequences. This paper is devoted to a study of the general properties of Nörlund double entire sequence space η ( Γ ) , Γ and also study some of the properties of η ( Γ ) and η ( Λ ) .

Nagarajan Subramanian and Umakanta Misra THE NÖRLUND ORLICZ SPACE OF DOUBLE GAI SEQUENCES

Let χ denotes the space of all double gai sequences. Let Λ denotes the space of all double analytic sequences. This paper is devoted to a study of the general properties of Nörlund double Orlicz space of gai sequence space η ( χM ) and χM . and Nörlund double Orlicz space of analytic sequence space η ( ΛM ) and ΛM .
