Convergence of matrix transform means with respect to Vilenkin systems
Miskolc Mathematical NotesIn this paper we discuss the convergence of matrix transform means of Vilenkin-Fourier series of integrable functions in Vilenkin-Lebesgue points, where the elements of the matrix rows are monotonic. We also prove convergence in

On the partial sums of Vilenkin-Fourier series
, 2014 The aim of this paper is to investigate weighted maximal operators of partial sums of Vilenkin-Fourier series. Also, the obtained results we use to prove approximation and strong convergence theorems on the martingale Hardy spaces Hp, when 0 The aim of ...

Many worlds in one: the search for other universes
, 2006 Among his peers, Alex Vilenkin is regarded as one of the most imaginative and creative cosmologists of our time. His contributions to our current understanding of the universe include a number of novel ideas, two of which--eternal cosmic inflation and ...

Almost everywhere convergence of Vilenkin-Fourier series of 𝐻¹ functions
, 1990 In [5] Ladhawala and Pankratz proved that if f f is in dyadic H 1 {H^1} , then any lacunary sequence of partial sums of the Walsh-Fourier series of f f converges a.e.

Fourier series on Vilenkin groups
, 1988 The focus of this investigation is pointwise convergence of Fourier series of functions defined on a compact Vilenkin group, i.e., a compact metrizable totally disconnected abelian group.

Translation invariant operators on Hardy spaces over Vilenkin groups
, 2004 We show that a number of well known multiplier theorems for Hardy spaces over Vilenkin groups follow immediately from a general condition on the kernel of the multiplier operator.

On an Estimate of the Partial Sums of Vilenkin-Fourier
, 1991 We show that the partial sums Snf of the Vilenkin-Fourier series of f ∊ L1 are of exponential type off any set where the Hardy-Littlewood maximal function of f is bounded. It then follows that Snkf(x) = o(log log nk) a.e.

Approximation by N\"orlund means with respect to Vilenkin system in Lebesgue spaces
, 2023 In this paper we improve and complement a result by M\'oricz and Siddiqi \cite{Mor}. In particular, we prove that their estimate of the N\"orlund means with respect to the Vilenkin system holds also without their additional condition.
