A sufficient condition for uniform convergence of double sine series with p-bounded variation coefficients
Mateusz Kubiak, Bogdan Szal
In the present paper we will introduce a new class of double sequences called DGM (p, alpha, beta, gamma, r), which is the generalization of a class considered by Szal and Duzinkie…

A sufficient condition for uniform convergence of trigonometric series with p-bounded variation coefficients
Mateusz Kubiak, Bogdan Szal
In this paper we consider trigonometric series with p-bounded variation coefficients. We presented a sufficient condition for uniform convergance of such series in case p > 1. This…
