Uniform Approximation in L0, infinity)-Space by Cesaro Means of Fourier-Laguerre Series

摘要

We study the problem to determine the degree of approximation of f is an element of L[0, infinity) by Cesaro means of order lambda >= 1 of the Fourier-Laguerre series of f for any x > 0: We prove the result for x - 0 separately.
