RH-regular transformation of unbounded double sequences [PDF]

open access: yes, 2013
At the Ithaca meeting in 1946 it was conjectured that it is possible to construct a two-dimensional regular summability matrix $A=\{a_{n,k}\}$ with the property that, for every real sequence $\{s_{k}\}$, the transformed sequence $$t_{n}=\sum_{k=0 ...

Generalized lacunary strong Zweier convergent sequence spaces [PDF]

open access: yes, 2016
In this paper we introduce generalized double Zweier lacunary convergent sequence spaces via sequence of Orlicz functions over n-normed spaces. We also make an effort to study some topological properties and inclusion relations between these spaces ...

Some classes of matrix transforms related to speed-Maddox spaces over ultrametric fields [PDF]

open access: yes
Let K be a complete, non-trivially valued, ultrametric (or non-archimedean) field, and λ = {λn} − a sequence in K with the property 0 < |λn| ↗ ∞, n ➝ ∞, i.e., the speed of convergence.

A characterization of holomorphic bivariate functions of bounded index [PDF]

open access: yes, 2017
The following notion of bounded index for complex entire functions was presented by Lepson. function f(z) is of bounded index if there exists an integer N independent of z, such that The main goal of this paper is extend this notion to holomorphic ...

On some classes of four dimensional regular matrices [PDF]

open access: yes, 2016
In 1981, Rath and Tripathy presented some classes of regular matrices such that every bounded sequence is limitable by some member of each class of ordinary conservative matrices using ordinary sequences.

Some matrix transformations and almost convergence [PDF]

open access: yes, 2013
The sequence space bv(u,p) has been defined and the classes (bv(u,p):l?), (bv(u,p):c),and (bv(u,p):c0) of infinite matrices have been characterized by Ba?ar, Altay and Mursaleen ( see, [2] ). The main purposes of the present paper is to characterize

Some saturation classes for deferred Riesz and deferred Nörlund means [PDF]

open access: yes
One of main problem in approximation theory is determining a saturation class for a given method. The problem of determining a saturation class has been considered by Zamanski, Sunouchi, Watari and others. Mohaparta and Russel have considered some direct

On $k$-Fibonacci sums by matrix methods [PDF]

open access: yes, 2014
In this paper, some $k$-Fibonacci and $k$-Lucas with arithmetic indexes sums are derived by using the matrices $R_{a}=\left[ \begin{array}{lr} L_{k,a} & -(-1)^{a} \\ 1 & 0 \end{array}\right]$ and $S_{a}=\frac{1}{2}\left[ \begin{array}{lr} L_{k,a ...

On fuzzy real-valued double A-sequence spaces defined by Orlicz function [PDF]

open access: yes, 2011
The purpose of this paper is to introduce and study a new concept of strong fuzzy real-valued double A- convergence sequences with respect to an Orlicz function. Also, some properties of the resulting fuzzy real-valued sequence spaces are examined.

Korovkin subsets in the sense of summation process [PDF]

open access: yes, 2018
In this paper we introduce Korovkin subsets for a positive linear operator T in the sense of summation process. The characterization of Korovkin subsets of C 0 (X), closure of the set of all functions with compact support on X, for a positive linear ...
