Absolute and Uniform Convergence of Spectral Expansion in the Eigenfunctions of a Third-Order Ordinary Differential Operator
Author:
Abstract: In this paper studied the convergence of spectral expansions of functions of the class W1 1 (G) ,G= (0,1) in eigenfunctions of an ordinary differential operator of third order with integral coefficients. Sufficient conditions for absolute and uniform convergence are obtained and the rate of uniform convergence of these expansions on the interval Gis found.
