Some new results for subsequences of Nörlund logarithmic means of Walsh-Fourier series
D. Baramidze, L. -E. Persson, H. Singh +1
We prove that there exists a martingale such that the subsequence of Nörlund logarithmic means with respect to the Walsh system are not bounded in the L…
Lebesgue and Vilenkin-Lebesgue points and a. e. Convergence of Nörlund means with respect to Vilenkin systems of integrable functions
Davit Baramidze, Zura Dvalashvili, Giorgi Tutberidze
In this paper we derive converge of Nörlund means of Vilenkin-Fourier series with monotone coefficients of integrable functions in Lebesgue and Vilinkin-Lebesgue points. Moreover,…
Lebesgue and Vilenkin-Lebesgue points and a.e. Convergence of T means with respect to Vilenkin systems of integrable functions
Davit Baramidze, Nato Gogolashvili, Nato Nadirashvili
In this paper we derive converge of means of Vilenkin-Fourier series with monotone coefficients of integrable functions in Lebesgue and Vilinkin-Lebesgue points. Moreover, we d…

Davit Baramidze
We discuss and type inequalities of weighted maximal operators of means with respect to the Vilenkin systems with monotone coefficients, con…
