On the Approximation Properties of Cesàro Means of Negative Order of double Vilenkin-Fourier Series

Tsitsino Tepnadze

In this paper we establish approximation properties of Cesàro means with $α, β$ $ε$ $(0, 1)$ of Vilenkin-Fourier series.This result allows one to obtain a condition whi…

On the Approximation Properties of Cesàro Means of Negative Order of Vilenkin-Fourier Series

Tsitsino Tepnadze

In this paper we establish approximation properties of Cesàro $(C, - α)$ means with $α$ $ε$ $(0, 1)$ of Vilenkin-Fourier series.This result allows one to obtain a condition which is s…
