Orthogonal Polynomial Wavelets

Numerical Algorithms, 2002
The authors construct orthogonal polynomial wavelets and extend some results of \textit{B. Fischer} and \textit{J. Prestin} [Math. Comput. 66, No. 220, 1593-1618 (1997; Zbl 0896.42020)]. Let \(P_j\) \((j= 0,1,\dots)\) be orthonormal polynomials on \([a,b]\) \((-\infty\leq a< b\leq\infty)\) with respect to a nonnegative weight function \(w\).

Orthogonal Polynomials Associated with Related Measures and Sobolev Orthogonal Polynomials

Numerical Algorithms, 2003
Let \(d\mu_1\) and \(d\mu_2\) be two measures with the same support \(E\). They are said to be related to each other by a first degree polynomial multiplication, if \[ (x-q)d\mu_1(x)=cd\mu_2(x), \] where the first degree polynomial \(c^{-1}(x-q)\) is positive on \(E\). The authors study the connection between two sequences of orthogonal polynomials and

Orthogonal Polynomials

1966
Publisher Summary This chapter focuses on simple sets of orthogonal polynomials. These sets of polynomials arise in various ways, one of which is as the solutions of a class of differential equations. It has been shown that, under certain conditions, given any interval and a positive weight function on that interval, there exists a corresponding set ...

On Multivariate Orthogonal Polynomials

SIAM Journal on Mathematical Analysis, 1993
Orthogonal polynomials in several variables are studied. The results include a newformulation of the recurrence relation, characterization of orthogonality of polynomial sequences, an analogy of Christoffel-Darboux formula, and properties of reproducing kernel function.

Orthogonal Polynomial Regression

International Statistical Review / Revue Internationale de Statistique, 1979
Summary We discuss in basic terms the orthogonal polynomial regression approach for curve fitting when the independent variable occurs at unequal intervals and is observed with unequal frequency. The computations required for determining orthogonal polynomials are described with a simple example.

ASYMPTOTICS OF ORTHOGONAL POLYNOMIALS

International Journal of Numerical Analysis and Modeling, 2018
In this survey article, we present some recent results on the asymptotic behavior of four systems of orthogonal polynomials. These are Stieltjes-Wigert, Hahn, Racah and pseudo-Jacobi polynomials. In each case, the variable $z$ is allowed to be in any part of the complex plane. In some cases, asymptotic formulas are also given for their zeros.
