A discretized Fourier orthogonal expansion in orthogonal polynomials on a cylinder
We study the convergence of a discretized Fourier orthogonal expansion in orthogonal polynomials on $B^2 \times [-1,1]$, where $B^2$ is the closed unit disk in $\RR^2$. The discretized expansion uses a finite set of Radon projections and provides an algorithm for reconstructing three dimensional images in computed tomography.

ABSTRACT Vending is an important sector in the daily lives of many people, and coffee is the most frequently consumed product in the European market. Like many other sectors, vending is responding to the challenge of sustainable development by taking various actions, such as offering increasingly ecologically sound coffee while maintaining/improving ...

Expressions of Legendre polynomials through Bernoulli polynomials
A formula for expanding Legendre polynomials in Bernoulli polynomials is considered. The relationship is established by using a formula of finite summation, obtained by applying the discrete orthogonal relation of the modified Lommel polynomials.

Discrete Fourier Analysis and Chebyshev Polynomials with G2 Group
The discrete Fourier analysis on the 30°-60°-90° triangle is deduced from the corresponding results on the regular hexagon by considering functions invariant under the group G2, which leads to the definition of four families generalized Chebyshev ...

The Fractional Orthogonal Derivative
This paper builds on the notion of the so-called orthogonal derivative, where an n-th order derivative is approximated by an integral involving an orthogonal polynomial of degree n.

Orthogonal Polynomials for a Class of Measures with Discrete Rotational Symmetries in the Complex Plane [PDF]
We obtain the strong asymptotics of polynomials $$p_n(\lambda )$$pn(λ), $$\lambda \in {\mathbb {C}}$$λ∈C, orthogonal with respect to measures in the complex plane of the form $$\begin{aligned} \hbox {e}^{-N(|\lambda |^{2s}-t\lambda ^s-\overline{t ...

A discrete orthogonal polynomials approach for fractional optimal control problems with time delay [PDF]
An efficient direct and numerical method has been proposed to approximate a solution of time-delay fractional optimal control problems. First, a class of discrete orthogonal polynomials, called Hahn polynomials, has been introduced and their properties ...
