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…

Triangular Fejér Summability of Two-Dimensional Walsh-Fourier series
György Gát, Ushangi Goginava
It is proved that the operators of the triangular-Fej{é}r-means of a two-dimensional Walsh--Fourier series are uniformly bounded from the dyadic Hardy spac…
