# Bessel Equation

## Bessel equation

[′bes·əl i′kwā·zhən]
(mathematics)
The differential equation z 2ƒ″(z) + z ƒ′(z) + (z 2-n 2)ƒ(z) = 0.

## Bessel Equation

a linear differential equation of the second order of the form

x2y” + xy’ + (x2 - p2)y = 0

where the parameter (“index”) p can take on arbitrary (complex) values. The equation is named for F. Bessel. Numerous physics problems reduce to this equation. The solutions of the Bessel equation are called cylinder functions.

Another approach to solving (26), one that does not require that it be recognized as a Bessel equation, is to use an iterative numerical method.
Directly or indirectly all three of these quantities result from solving the Bessel equation (26), which, itself, is derived from the substitute equation (13), not from the fundamental, definition of a force-free current (12).

the Bessel equation is LCO, LCN, or LP in different ranges of parameter v--it is easier to ask a user to input such parameter ranges manually and check them, rather than write an algorithm to determine the ranges automatically.
One of these yields the factor [Mathematical Expression Omitted], and the other is a Bessel equation.
By using the separation of variables, the magnetic field equations in regions II, III and IV governed by the Laplace's equation can be decomposed into a Helmholtz equation and a Bessel equation.
