APPLICATIONS OF CES ARO SUBMETHOD TO APPROXIMATION OF FUNCTIONS IN WEIGHTED ORLICZ SPACES

Abstract

In this work, the approximation properties of the matrix submethods in weighted Orlicz spaces with Muckenhoupt weights are studied. We obtain some results related to trigonometric approximation using matrix submethods of partial sums of Fourier series of functions in the weighted Orlicz spaces with Muckenhoupt weights.The degree of trigonometric approximations by the matrix methods to the functions have been investigated in weighted Orlicz spaces with Muckenhoupt weights. The error of estimations in this work is obtained in more general terms. In many studies the classical Cesaro method was used to obtain the estimations. In this study to obtain these estimations we use Cesaro submethod instead of classical Cesaro method.
