Strong Summability of Two-Dimensional Vilenkin Fourier series
Ushangi Goginava
In this paper we study the exponential uniform strong summability of two-dimensional Vilenkin-Fourier series. In particular, it is proved that the two-dimensional Vilenkin-Fourier…
Strong Approximation by Marcinkiewicz Means of two-dimensional Walsh-Kaczmarz-Fourier Series
Ushangi Goginava, Karoly Nagy
In this paper we study the exponential uniform strong approximation of Marcinkiewicz type of two-dimensional Walsh-Kaczmarz-Fourier series. In particular, it is proved that the Mar…
Pointwise convergence of Marcinkiewicz-Fejer means of double Vilenkin-Fourier series
Ushangi Goginava
In this paper we give a characterization of points in which Marcinkiewicz-Fejer means of double Vilenkin-Fourier series converges.
Almost Everywhere Strong Summability of Fejer means of rectangular partial sums of two-dimensional Walsh-Fourier Series
Ushangi Goginava
It is proved a BMO-estimation for rectangular partial sums of two-dimensional Walsh-Fourier series from which it is derived an almost everywhere exponential summability of rectangu…
