Summability Of Fourier Orthogonal Expansions And A Discretized Fourier Orthogonal Expansion Involving Radon Projections For Functions On The Cylinder.

Overview

We investigate Cesaro summability of the Fourier orthogonal expansion of functions on Bd x I m, where Bd is the closed unit ball in Rd and Im is the m-fold Cartesian product of the interval [-1, 1], in terms of orthogonal polynomials with respect to the weight functions (1 - z) alpha(1 + z)beta(1 - |x|2)lambda-1/2 , with z ∈ Im and x ∈ Bd. In addition, we study a discretized Fourier orthogonal expansion on the cylinder B2 x [-1, 1], which uses a finite number of Radon projections. The Lebesgue constant of this ...

Overview

We investigate Cesaro summability of the Fourier orthogonal expansion of functions on Bd x I m, where Bd is the closed unit ball in Rd and Im is the m-fold Cartesian product of the interval [-1, 1], in terms of orthogonal polynomials with respect to the weight functions (1 - z) alpha(1 + z)beta(1 - |x|2)lambda-1/2 , with z ∈ Im and x ∈ Bd. In addition, we study a discretized Fourier orthogonal expansion on the cylinder B2 x [-1, 1], which uses a finite number of Radon projections. The Lebesgue constant of this operator is obtained, and the proof utilizes generating functions for associated orthogonal series.
