Approximation of a Function in Hölder Class Using Double Karamata (Kλ,μ) Method

Approximation of a Function in Hölder Class Using Double Karamata (Kλ,μ) Method

In this paper, we establish a new theorem on the best approximation of a function of two variables belonging to H ̈older class by double Karamata (Kλ,μ) means of its double Fourier series.
