#### On double statistical p-convergence of fuzzy numbers

(Springer International Publishing AG, 2009)

Savas and Mursaleen defined the notions of statistically convergent and statistically Cauchy for double sequences of fuzzy numbers. In this paper, we continue the study of statistical convergence by proving some theorems. ...

#### On (Lambda) over-bar-statistically convergent double sequences of fuzzy numbers

(Springer International Publishing AG, 2008)

We study the notion of (lambda) over bar -statistically convergent for double sequence of fuzzy numbers and also get some inclusion relations. Copyright (C) 2008 Ekrem Savas.

#### On general summability factor theorems

(Springer International Publishing AG, 2007)

The goal of this paper is to obtain sufficient and (different) necessary conditions for a series Sigma a(n), which is absolutely summable of order k by a triangular matrix method A, 1 < k <= s < infinity, to be such that ...

#### (Lambda) over-bar-double sequence spaces of fuzzy real numbers defined by Orlicz function

(Univ Osijek, 2009-12)

In this paper we define and study two concepts which arise from the notion of de la Vallee-Poussin means, namely: strongly double (lambda) over bar -convergence defined by Orlicz function and (lambda) over bar -statistical ...

#### A recent note on quasi-power increasing sequence for generalized absolute summability

(Springer, 2009)

We prove two theorems on vertical bar A,delta vertical bar(k), k >= 1,0 <= delta < 1/k, summability factors for an infinite series by using quasi-power increasing sequences. We obtain sufficient conditions for Sigma ...

#### A note on |A|(K) summability factors for infinite series

(Springer, 2007)

We obtain sufficient conditions on a nonnegative lower triangular matrix A and a sequence lambda(n) for the series Sigma a(n)lambda(n)/na(nn) to be absolutely summable of order k >= 1 by A. Copyright (c) 2007 E. Savas, and ...

#### Some l(p)-type new sequence spaces and their geometric properties

(Hindawi Publishing Corporation, 2009)

We introduce an l(p)-type new sequence space and investigate its some topological properties including AK and AD properties. Besides, we examine some geometric properties of this space concerning Banach-Saks type p and ...

#### On absolute cesaro summability

(Springer International Publishing AG, 2009)

Denote by A(k) the sequence space defined by A(k) = {(s(n)) : Sigma(infinity)(n=1) n(k-1)vertical bar a(n)vertical bar(k) < infinity, a(n) = s(n) - s(n-1)} for k >= 1. In a recent paper by E. Savas, and H. Sevli (2007), ...

#### Summability of double independent random variables

(Hindawi Publishing Corporation, 2008)

We will examine double sequence to double sequence transformation of independent identically distribution random variables with respect to four-dimensional summability matrix methods. The main goal of this paper is the ...

#### A note on generalized vertical bar a vertical bar(K)- summability factors for infinite series

(Springer International Publishing AG, 2010)

A general theorem concerning the |A|(k)-summability factors of infinite series has been proved.
