Connection Coefficients of Orthogonal Polynomials

open access: yesCanadian Mathematical Bulletin, 1992
Let be polynomials orthogonal with respect to different distributions. Conditions are given which imply that the coefficients in the expansion of Pn in terms of Q0, Q1,..., Qn are non-negative.

Connection coefficients on an interval and wavelet solutions of Burgers equation

open access: yesJournal of Computational and Applied Mathematics, 2001
A definition of connection coefficients is introduced and techniques of computation are presented. We use semi-implicit time difference scheme to solve Burgers equation by applying the evaluations of connection coefficients in calculating the integrals ...

Recurrence relations for connection coefficients between two families of orthogonal polynomials

open access: yesJournal of Computational and Applied Mathematics, 1995
We describe a simple approach in order to build recursively the connection coefficients between two families of orthogonal polynomial solutions of second- and fourth-order differential ...

Numerical identification of position-dependent friction coefficients from measured displacement data in a bolt-nut connection

open access: yesResults in Engineering, 2023
Friction is a complex system affected by microscopical effects and multidisciplinary phenomena. Coulomb's simple friction model with a constant friction coefficient cannot account for all these tribological effects.

Recurrence relations for the connection coefficients of orthogonal polynomials of a discrete variable

open access: yesJournal of Computational and Applied Mathematics, 1996
We give explicitly recurrence relations satisfied by the connection coefficients between two families of the classical orthogonal polynomials of a discrete variable (i.e., associated with the names of Charlier, Meixner, Krawtchouk and Hahn).

On Stokes Matrices in terms of Connection Coefficients

open access: yesFunkcialaj Ekvacioj, 2016
: The classical problem of computing a complete system of Stokes multipliers of a linear system of ODEs of rank one in terms of some connection coefficients of an associated hypergeometric system of ODEs, is solved with no genericness assumptions on the ...

Connection and linearization coefficients of the Askey–Wilson polynomials

open access: yesJournal of Symbolic Computation, 2013
The linearization problem is the problem of finding the coefficients C"k(m,n) in the expansion of the product P"n(x)Q"m(x) of two polynomial systems in terms of a third sequence of polynomials R"k(x),P"n(x)Q"m(x)=@?k=0n+mC"k(m,n)R"k(x). The polynomials P"n, Q"m and R"k may belong to three different polynomial families.

Linearization and connection coefficients of polynomial sequences: A matrix approach

open access: yesLinear Algebra and its Applications, 2023
For a sequence of polynomials $\{p_k(t)\}$ in one real or complex variable, where $p_k$ has degree $k$, for $k\ge 0$, we find explicit expressions and recurrence relations for infinite matrices whose entries are the coefficients $d(n,m,k)$, called ...

A recurrence relation for generalised connection coefficients

open access: yesJournal of Computational Dynamics
We formulate and prove a general recurrence relation that applies to integrals involving orthogonal polynomials and similar functions. A special case are connection coefficients between two sets of orthonormal polynomials, another example is integrals of products of Legendre functions.
