11: 18.39 Applications in the Physical Sciences

… ►where $x$ is a spatial coordinate, $m$ the mass of the particle with potential energy $V(x)$, $\mathrm{\hslash }=h/(2\pi )$ is the reduced Planck’s constant, and $(a,b)$ a finite or infinite interval. … ►Below we consider two potentials with analytically known eigenfunctions and eigenvalues where the spectrum is entirely point, or discrete, with all eigenfunctions being $L^2$ and forming a complete set. … ►This indicates that the Laguerre polynomials appearing in (18.39.29) are not classical OP’s, and in fact, even though infinite in number for fixed $l$, do not form a complete set. … ►For the potential $V(r)=+Z{e}^2/r$, corresponding to interaction of particles with like charges, there are no bound states, the continuum scattering states form a complete set for each $l$, as discussed in Chapter 33, and their discretized versions in §18.39(iv). … ►For many applications the natural weight functions are non-classical, and thus the OP’s and the determination of the Gaussian quadrature points and weights represent a computational challenge. …

12: 25.12 Polylogarithms

… ►The notation ${\mathrm{Li}}_2\left(z\right)$ was introduced in Lewin (1981) for a function discussed in Euler (1768) and called the dilogarithm in Hill (1828): … ►In the complex plane ${\mathrm{Li}}_2\left(z\right)$ has a branch point at $z=1$. … ►valid when $\mathrm{\Re }s>0$, $\mathrm{\Im }a>0$ or $\mathrm{\Re }s>1$, $\mathrm{\Im }a=0$. … ►Sometimes the factor $1/\mathrm{\Gamma }\left(s+1\right)$ is omitted. … ►For a uniform asymptotic approximation for $F_s(x)$ see Temme and Olde Daalhuis (1990).

14: 18.40 Methods of Computation

… ►

A numerical approach to the recursion coefficients and quadrature abscissas and weights

… ►A simple set of choices is spelled out in Gordon (1968) which gives a numerically stable algorithm for direct computation of the recursion coefficients in terms of the moments, followed by construction of the J-matrix and quadrature weights and abscissas, and we will follow this approach: Let $N$ be a positive integer and define … ►Results of low ($2$ to $3$ decimal digits) precision for $w(x)$ are easily obtained for $N\sim 10$ to $20$. … ►The quadrature points and weights can be put to a more direct and efficient use. … ►This allows Stieltjes–Perron inversion for the $w(x_{i,N})$, given the quadrature weights and points. …
