Approximation by matrix transform means with respect to the Walsh system in Lebesgue spaces
Authors:
István Blahota 
and Dóra Nagy
Abstract:
In this paper, we improve, complement and generalize (from Nörlund to matrix transform means) a result of Móricz and Siddiqi [26] and some statements of Areshidze and Tephnadze [3], and (from $T$ (weighted) to matrix transform means) Anakidze et al. [2].
Keywords: Fourier series, Walsh—Paley system, rate of approximation, matrix transform means
