Almost Everywhere Convergence of Convolution Measures

open access: yesCanadian Mathematical Bulletin, 2012
AbstractLet (X, ℬ, m, τ) be a dynamical system with (X, ℬ, m) a probability space and τ an invertible, measure preserving transformation. This paper deals with the almost everywhere convergence in L1(X) of a sequence of operators of weighted averages.

Order convergence and convergence almost everywhere revisited [PDF]

open access: yes, 2010
In Analysis two modes of non-topological convergence are interesting: order convergence and convergence almost everywhere. It is proved here that oder convergence of sequences can be induced by a limit structure, even a finest one, whenever it is considered in sigma-distributive lattices.

Almost everywhere convergence for noncommutative spaces

Banach Journal of Mathematical Analysis, 2022
The authors introduce various notions of almost uniform and almost everywhere convergence in Haagerup \(L^p\)-spaces over an arbitrary von Neumann algebra, using spectral projections of the operators in the sequence under consideration. These are first demonstrated in the case of a semifinite von Neumann algebra.

Mean and Almost Everywhere Convergence of Fourier–Neumann Series [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 1999
Let Jμ denote the Bessel function of order μ. The functions x−α/2−β/2−1/2Jα+β+2n+1(x1/2), n=0,1,2,…, form an orthogonal system in L2((0,∞),xα+βdx) when α+β>−1. In this paper we analyze the range of p, α, and β for which the Fourier series with respect to

On the Almost Everywhere Convergence of Multiple Fourier-Haar Series

open access: yesJournal of Contemporary Mathematical Analysis, 2019
The paper deals with the question of convergence of multiple Fourier-Haar series with partial sums taken over homothetic copies of a given convex bounded set W⊂R+n containing the intersection of some neighborhood of the origin with R+n. It is proved that

Convergence Almost Everywhere of Partial Sums and Féjer Means of Vilenkin–Fourier Series

open access: yesMediterranean Journal of Mathematics
We characterize subsequences {Snk} of partial sums with respect to (bounded or unbounded) Vilenkin systems of f ∈ L1(Gm) for which almost everywhere convergence holds.
