Maximal operators of Fejér means of Walsh-Kaczmarz-Fourier series
The main aim of this paper is to prove that there exists a martingale f∈ H1/2 such that the maximal Fejér operator with respect to Walsh-Kaczmarz system does not belong to the space L1/2. For the two-dimensional case, we prove that there exists a martingale f∈H1/2□(f∈H1/2) such that the restricted (...
