Abstract

Define the two dimensional diagonal Sunouchi operator

where S2n, 2n ƒ and σ2n ƒ are the (2n, 2n)th cubic-partial sums and 2nth Marcinkiewicz–Fejér means of a two-dimensional Walsh–Fourier series. The main aim of this paper is to prove that the operator is bounded from the Hardy space H1/2 to the weak L1/2 space and is not bounded from the Hardy space H1/2 to the space L1/2.
