Infinite matrices and absolute almost convergence [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1983
In 1973, Stieglitz [5] introduced a notion of FB-Convergence which provided a wide generalization of the classical idea of almost convergence due to Lorentz [1].

Almost sure convergence on chaoses [PDF]

open access: yesProceedings of the American Mathematical Society, 2019
We present several new phenomena about almost sure convergence on homogeneous chaoses that include Gaussian Wiener chaos and homogeneous sums in independent random variables. Concretely, we establish the fact that almost sure convergence on a fixed finite sum of chaoses forces the almost sure convergence of each chaotic component ...

Almost λr-Statistical and Strongly Almost λr-Convergence of Order β of Sequences of Fuzzy Numbers [PDF]

open access: yesJournal of Function Spaces, 2015
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.

Quasi-Almost Lacunary Statistical Convergence of Sequences of Sets [PDF]

open access: yesInternational Journal of Analysis and Applications, 2018
In this study, we defined concepts of Wijsman quasi-almost lacunary convergence, Wijsman quasi-strongly almost lacunary convergence and Wijsman quasi q-strongly almost lacunary convergence.

Almost statistical convergence in amenable semigroups [PDF]

open access: yesMATHEMATICA SCANDINAVICA, 2012
The purpose of this study is to extend the notion of almost statistical convergence to functions defined on discrete countable amenable semigroups.

On absolute almost convergence [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 1991
By analogy with the sequence space \(\ell_ p\) \((p>0)\), the concept of \(\hat\ell_ p\) was first introduced in [the authors, Trans. Am. Math. Soc. 283, 729-739 (1984; Zbl 0546.46004)]. In this paper the authors present certain negative results for \(\hat\ell_ p\).

NEW TYPE OF ALMOST CONVERGENCE [PDF]

open access: yes, 2021
In [1] for a given sequence $(\lambda_{n})$ with $\lambda_{n}< \lambda_{n+1}  \rightarrow \infty$ a new summability method $C_{\lambda}$ was introduced which generalizes the classical Ces\`{a}ro method.

On regular almost convergence [PDF]

open access: yesMathematical Communications, 1996
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 and columns are characterized; also, a theorem on the principal limit and on row (as well as column)

Almost sure exponential stability of the Euler–Maruyama approximations for stochastic functional differential equations [PDF]

open access: yes, 2011
By the continuous and discrete nonnegative semimartingale convergence theorems, this paper investigates conditions under which the Euler–Maruyama (EM) approximations of stochastic functional differential equations (SFDEs) can share the almost sure ...

The surprising almost everywhere convergence of Fourier–Neumann series [PDF]

open access: yes, 2009
For most orthogonal systems and their corresponding Fourier series, the study of the almost everywhere convergence for functions in Lp requires very complicated research, harder than in the case of the mean convergence.
