$u\!+\!\mathrm i v=\mathrm{korias}(x\!+\!\mathrm i y)$
  +
  +
==Description==
  +
  +
For $z\ne1$, funciton [[kori]] appears as
  +
  +
$\mathrm{kori}(z)=\displaystyle \frac{J_0\big( L \sqrt{z} \big)}{1-z}$
  +
  +
where $L$ is first zero of the Bessel function $J_0$. The corresponding limit for $z=1$ is assumed.
  +
  +
At large values of the argument, $|z|\gg 1$, the asymptotic approximation appears as [[korias]] defined with
  +
  +
$
  +
\mathrm{korias}_m(x) = - \sqrt{\frac{2}{\pi L_1}} x^{-5/4} \, G_m(x)\, \cos\left( - \frac{\pi}{4} + L_1 \sqrt{x}\, F_m(x) \right)
  +
$
  +
  +
where <br>
  +
$G_m(x) = \sum_{n=0}^{m} g_n x^{-n}$ <br>
  +
$F_m(x) = \sum_{n=0}^{m} f_n x^{-n}$
  +
  +
Coefficients $f$ and $g$ are estimated from the asymptotic expansion of function [[besselJ0]]. Approximaitons of these coefficients can be extracted from the code below.
  +
  +
The map corresponds to $\,m\!=\!11\,$.
  +
  +
The approximation fails in vicinity of zero and at $|z|$ of order of unity.
  +
  +
The approximation is good for $|z|\gg 1$. In particular, for $\Re(z)>40$,
  +
  +
$|\mathrm{korias}(z) - \mathrm{kori}(z)| < 10^{-15}$
  +
  +
The approximation is designed for evaluation of integrand for the contour integral for function [[maga]].

Complex map of asymptotic approximation korias with 11 terms of function kori.

$u\!+\!\mathrm i v=\mathrm{korias}(x\!+\!\mathrm i y)$

Description

For $z\ne1$, funciton kori appears as

$\mathrm{kori}(z)=\displaystyle \frac{J_0\big( L \sqrt{z} \big)}{1-z}$

where $L$ is first zero of the Bessel function $J_0$. The corresponding limit for $z=1$ is assumed.

At large values of the argument, $|z|\gg 1$, the asymptotic approximation appears as korias defined with

$ \mathrm{korias}_m(x) = - \sqrt{\frac{2}{\pi L_1}} x^{-5/4} \, G_m(x)\, \cos\left( - \frac{\pi}{4} + L_1 \sqrt{x}\, F_m(x) \right) $

where
$G_m(x) = \sum_{n=0}^{m} g_n x^{-n}$
$F_m(x) = \sum_{n=0}^{m} f_n x^{-n}$

Coefficients $f$ and $g$ are estimated from the asymptotic expansion of function besselJ0. Approximaitons of these coefficients can be extracted from the code below.

The map corresponds to $\,m\!=\!11\,$.

The approximation fails in vicinity of zero and at $|z|$ of order of unity.

The approximation is good for $|z|\gg 1$. In particular, for $\Re(z)>40$,

$|\mathrm{korias}(z) - \mathrm{kori}(z)| < 10^{-15}$

The approximation is designed for evaluation of integrand for the contour integral for function maga.
