Bessel Equation

Bessel Equation. Bessel's equation \eqref{eqbessel.1} is a special case of a confluent hypergeometric equation.since x = 0 is a regular singular point for the bessel equation, one of its solution can be bounded at this point but another linearly independent solution should be unbounded. As a consequence, we say that the bessel function of the rst kind satis es the equation u00(z) + 1 z u0(z) + 1 2 z2 u(z) = 0;
