Weighted almost convergence and related infinite matrices [PDF]
The purpose of this paper is to introduce the notion of weighted almost convergence of a sequence and prove that this sequence endowed with the sup-norm ∥ ⋅ ∥ ∞ ${\Vert \cdot \Vert } _{\infty}$ is a BK-space. We also define the notions of weighted almost

On Absolutely Almost Convergence
In this paper, we study (Pn, s)-absolutely almost convergence where npn = 0(Pn) as n→ ∞,Pn = ∑n ν=0 pν and s > 0. We also give necessary and sufficient conditions for a summability matrix to be (λn, s)-absolutely almost conservative, and obtain some ...

Generalized Almost Convergence and Core Theorems of Double Sequences
The idea of [λ, μ]-almost convergence (briefly, F[λ, μ]-convergence) has been recently introduced and studied by Mohiuddine and Alotaibi (2014). In this paper first we define a norm on F[λ, μ] such that it is a Banach space and then we define and ...

Almost λr-Statistical and Strongly Almost λr-Convergence of Order β of Sequences of Fuzzy Numbers
The main purpose of this article is to introduce the concepts of almost λr-statistical convergence and strongly almost λr-convergence of order β of sequences of fuzzy numbers with respect to an Orlicz function.

Order summability and almost convergence [PDF]
The object of this paper is to compare the summability methods of almost convergence and order summability. This is done by examining a method of summability which includes both methods. The main result is that every monotone Fourier effective matrix is strongly regular.

Wavelets: convergence almost everywhere [PDF]
It has been proved in [7], using the Carleson-Hunt theorem on the pointwise convergence of Fourier series, that the wavelet inversion formula is valid pointwise for all L^p -functions, and also without restrictions on ...

On regular almost convergence [PDF]
In this paper possible regularity definitions for almost convergent double sequences are considered as generalizations of the regular convergence in the sense of G. H. Hardy and F.Móricz. Classes of almost convergent sequences with almost convergent rows

Almost convergence of complex uncertain double sequences
Convergence of real sequences, as well as complex sequences are studied by B. Liu and X. Chen respectively in uncertain environment. In this treatise, we extend the study of almost convergence by introducing double sequences of complex uncertain ...

On the Spaces of $\lambda _{r}$-almost Convergent and $\lambda _{r}$-almost Bounded Sequences [PDF]
The aim of the present work is to introduce the concept of $\lambda _{r}$-almost convergence of sequences. We define the spaces $f\left( \lambda _{r}\right) $ and $f_{0}\left( \lambda _{r}\right) $ of $ \lambda _{r}$-almost convergent and $\lambda _{r ...
