On the divergence of subsequences of partial Walsh-Fourier sums
Ushangi Goginava, Giorgi Oniani
A class of increasing sequences of natural numbers is found for which there exists a function such that the subsequence of partial Walsh-Fourier sums $(S_{n_k…
Conjugate Transforms on Dyadic Group
Ushangi Goginava, Aleksandre Saatashvili
In this paper we study the properties of the Lebesgue constant of the conjugate transforms. For conjugate Fejér means we will find necessary and sufficient condition on for whi…
Logarithmic means of Walsh-Fourier Series
Ushangi Goginava
In this paper we discuss some convergence and divergence properties of subsequences of logarithmic means of Walsh-Fourier series . We give necessary and sufficient conditions for t…
On almost everywhere exponential summability of rectangular partial sums of double trigonometric Fourier series
Ushangi Goginava, Grigori Karagulyan
In this paper we study the a.e. exponential strong summability problem for the rectangular partial sums of double trigonometric Fourier series of the functions from .
Convergence in Measure of Strong logarithmic means of double Fourier series
Ushangi Goginava, Larry Gogoladze
Nörlund strong logarithmic means of double Fourier series acting from space into space are studied. The maximal Orlicz…
Convergence of logarithmic means of quadratical partial sums of double Fourier series
Ushangi Goginava
In this paper we investigate some convergence and divergence properties of the logarithmic means of quadratical partial sums of double Fourier series of functions in the measure an…
