General Lebesgue Constants for Linear Mean Subsequences of Fourier Sums
L. P. Falaleev Institute of Mathematics, Ministry of Education and Science of the Republic of Kazakhstan
Abstract:
Simple sufficient conditions for the boundedness of the norms of the general matrix operators constructed from the subsequences of partial sums of trigonometric Fourier series with polynomial order of growth are obtained. They guarantee a particular rate of approximation for subclasses of continuous functions.
