Mean and Almost Everywhere Convergence of Fourier–Neumann Series

Journal of Mathematical Analysis and Applications, 1999
Let J denote the Bessel function of order . The functions x-/2-/2-1/2J++2n+1(x 1/2), n=0,1,2,..., form an orthogonal system in L2((0,),x+dx) when +-1. In this paper we analyze the range of p, , and for which the Fourier series with respect to this system converges in the Lp((0,),xdx)-norm. Also, we describe the space in which the span of the system is
