Discrete Bessel functions and transform

math-ph · 2020-05-12 · unverdicted · novelty 6.0

Discrete Bessel functions B_n^{(N)}(m) are constructed via N-point Fourier restriction on the circle, satisfy exact analogues of continuous relations including Graf's formulas, and approximate J_n(m) closely for n + |m| < N.

Discrete Bessel and Mathieu functions

math-ph · 2021-02-09 · unverdicted · novelty 5.0

Discrete Bessel and Mathieu functions are introduced as N-point Fourier-sum approximants to the continuous special functions via separation of variables under discrete dihedral symmetry.
