q-Hermite Polynomials and Classical Orthogonal Polynomials [PDF]

open access: yesCanadian Journal of Mathematics, 1996
AbstractWe use generating functions to express orthogonality relations in the form of q-beta. integrals. The integrand of such a q-beta. integral is then used as a weight function for a new set of orthogonal or biorthogonal functions. This method is applied to the continuous q-Hermite polynomials, the Al-Salam-Carlitz polynomials, and the polynomials ...

Asymptotic Computation of Classical Orthogonal Polynomials [PDF]

open access: yes, 2021
The classical orthogonal polynomials (Hermite, Laguerre and Jacobi) are involved in a vast number of applications in physics and engineering. When large degrees $n$ are needed, the use of recursion to compute the polynomials is not a good strategy for computation and a more efficient approach, such as the use of asymptotic expansions,is recommended.

Nearest Neighbor Recurrence Relations for Meixner–Angelesco Multiple Orthogonal Polynomials of the Second Kind

open access: yesMathematics, 2023
This paper studies a new family of Angelesco multiple orthogonal polynomials with shared orthogonality conditions with respect to a system of weight functions, which are complex analogs of Pascal distributions on a legged star-like set.

Orthogonal Polynomials on the Unit Ball and Fourth-Order Partial Differential Equations [PDF]

open access: yes, 2016

d-Orthogonal Analogs of Classical Orthogonal Polynomials [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2018
Classical orthogonal polynomial systems of Jacobi, Hermite and Laguerre have the property that the polynomials of each system are eigenfunctions of a second order ordinary differential operator. According to a famous theorem by Bochner they are the only systems on the real line with this property.

Orthogonal Polynomials and Related Special Functions Applied in Geosciences and Engineering Computations

open access: yesCommunications, 2010
In applications of mathematics involving either the Laplace or the Helmholtz equation in spherical coordinates the associated Legendre equation occurs. Its solutions are called associated Legendre functions. They have some relations to classical Legendre

On 2-orthogonal polynomials of Laguerre type

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
Let {Pn}n≥0 be a sequence of 2-orthogonal monic polynomials relative to linear functionals ω0 and ω1 (see Definition 1.1). Now, let {Qn}n≥0 be the sequence of polynomials defined by Qn:=(n+1)−1P′n+1,n≥0.

A conjecture on Exceptional Orthogonal Polynomials [PDF]

open access: yes, 2012
Exceptional orthogonal polynomial systems (X-OPS) arise as eigenfunctions of Sturm-Liouville problems and generalize in this sense the classical families of Hermite, Laguerre and Jacobi. They also generalize the family of CPRS orthogonal polynomials.

Classical Sobolev Orthogonal Polynomials: Eigenvalue Problem [PDF]

open access: yesResults in Mathematics, 2019
We consider the discrete Sobolev inner product $$(f,g)_S=\int f(x)g(x)d +Mf^{(j)}(c)g^{(j)}(c), \quad j\in \mathbb{N}\cup\{0\}, \quad c\in\mathbb{R}, \quad M>0, $$ where $ $ is a classical continuous measure with support on the real line (Jacobi, Laguerre or Hermite).
