Some inequalities for Cesàro means of double Vilenkin–Fourier series
In this paper, we state and prove some new inequalities related to the rate of [Formula: see text] approximation by Cesàro means of the quadratic partial sums of double Vilenkin–Fourier series of functions from [Formula: see text] .
