On the degree of aproximation of a periodic function f almost Riesz- means of its conjugate series
The present paper is concerned with the degree of approximation of certain functions belonging to the class Lip (p(t), p) by almost Riesz means. 1. Let f be a 27t-periodic function integrable Lp (p > 1) and let f >—’ + S (an Cos nx -f- bn Sin nx) (1.1) n=-l be its Fourier series.
