In this contribution, we use the connection between stable polynomials and orthogonal polynomials on the real line to construct sequences of Hurwitz polynomials that are robustly stable in terms of several uncertain parameters.

Fourier Transform of the Orthogonal Polynomials on the Unit Ball and Continuous Hahn Polynomials
Some systems of univariate orthogonal polynomials can be mapped into other families by the Fourier transform. The most-studied example is related to the Hermite functions, which are eigenfunctions of the Fourier transform.

A Note on Bi-Orthogonal Polynomials and Functions
The theory of orthogonal polynomials is well established and detailed, covering a wide field of interesting results, as, in particular, for solving certain differential equations.

Free-Fermion entanglement and orthogonal polynomials [PDF]
We present a simple construction for a tridiagonal matrix T that commutes with the hopping matrix for the entanglement Hamiltonian of open finite free-Fermion chains associated with families of discrete orthogonal polynomials.

Planar orthogonal polynomials as Type II multiple orthogonal polynomials [PDF]
We show that the planar orthogonal polynomials with l logarithmic singularities in the potential are the multiple orthogonal polynomials (Hermite–Padé polynomials) of Type II with l measures.

On Differential Equations Associated with Perturbations of Orthogonal Polynomials on the Unit Circle
In this contribution, we propose an algorithm to compute holonomic second-order differential equations satisfied by some families of orthogonal polynomials.

The Stenger conjectures and the A-stability of collocation Runge-Kutta methods
Stenger conjectures are claims about the location of the eigenvalues of matrices whose elements are certain integrals involving basic Lagrange interpolating polynomials supported on the zeros of orthogonal polynomials. In this paper, we show the validity
