On the approximation properties of Cesàro means of negative order of double Vilenkin – Fourier series
UDC 517.5 We establish approximation properties of Ces\`{a}ro $% (C,-\alpha ,-\beta)$ means with $\alpha ,\beta $ $\epsilon $ $(0,1)$ of Vilenkin\,--\,Fourier series. This result allows one to obtain a condition which is sufficient for the converge...
