Almost everywhere convergence of Cesàro means of two variable Walsh – Fourier series with varying parameteres
Keyword(s):
UDC 517.5 We prove that the maximal operator of some means of cubical partial sums of two variable Walsh – Fourier series of integrable functions is of weak type . Moreover, the -means of the function converge a.e. to for , where is the Walsh group for some sequences .
