Generalized Lacunary Statistical Difference Sequence Spaces of Fractional Order

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
We generalize the lacunary statistical convergence by introducing the generalized difference operator Δνα of fractional order, where α is a proper fraction and ν=(νk) is any fixed sequence of nonzero real or complex numbers.

I_2-Cesàro summability of double sequences of sets [PDF]

open access: yes, 2020
In this paper, we defined concept of Wijsman I_2-Cesàro summability and investigate the relationships between the concepts of Wijsman strongly I_2-Cesàro summability, Wijsman strongly I_2-lacunary convergence, Wijsman p-strongly I_2-Cesàro summability and

Strong Convergence on Iterative Methods of Cesàro Means for Nonexpansive Mapping in Banach Space

open access: yesAbstract and Applied Analysis, 2014
Two new iterations with Cesàro's means for nonexpansive mappings are proposed and the strong convergence is obtained as n→∞. Our main results extend and improve the corresponding results of Xu (2004), Song and Chen (2007), and Yao et al. (2009).

Agricultural Diversification at the Margin. Strategies and Determinants in Italian Mountain and Remote Areas

open access: yesAgribusiness, Volume 42, Issue 4, Page 2091-2100, Autumn 2026.
ABSTRACT This paper explores the convergence in on‐farm diversification strategies of agricultural holdings, between remote areas and more central ones. Using Italian farm‐level data, we explore the determinants of diversification strategies across farms.

Equidistribution in 2‐nilpotent Polish groups and triple restricted sumsets

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract The aim of this paper is to establish a Ratner‐type equidistribution theorem for orbits on homogeneous spaces associated with 2$\hskip.001pt 2$‐nilpotent locally compact Polish groups under the action of a countable discrete abelian group.

On Elliott's conjecture and applications

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 3, September 2026.
Abstract Let f:N→D$f:\mathbb {N}\rightarrow \mathbb {D}$ be a multiplicative function. Under the merely necessary assumption that f$f$ is nonpretentious (in the sense of Granville and Soundararajan), we show that for any pair of distinct integer shifts h1,h2$h_1,h_2$, the two‐point correlation 1x∑n⩽xf(n+h1)f¯(n+h2)$$\begin{equation*} \frac{1}{x}\sum _ ...

Remarks on several types of convergence of bounded sequences [PDF]

open access: yes, 2006
summary:In this paper we analyze relations among several types of convergences of bounded sequences, in particulars among statistical convergence, ${\cal I}_u$-convergence, $\varphi $-convergence, almost convergence, strong $p$-Cesàro convergence and ...

Completeness of a Normed Space via Strong p-Cesàro Summability [PDF]

open access: yes, 2019
In this paper we will characterize the completeness and barrelledness of a normed space through the strong p-Cesàro summability of series. A new characterization of weakly unconditionally Cauchy series and unconditionally convergent series through the ...
