An exact constant on the estimation of the approximation of classes of periodic functions of two variables by Ceśaro means
In the present work, we study problem related to the approximation of continuous $2\pi$-periodic functions by linear means of their Fourier series. The simplest example of a linear approximation of periodic function is the approximation of this function by partial sums of the Fourier series. However...
