Definition:Hypergeometric Differential Equation

Definition
A hypergeometric differential equation is a second order ODE of the form:


 * $x \paren {1 - x} \dfrac {\d^2 y} {\d x^2} + \paren {c - \paren {a + b + 1} x} \dfrac {\d y} {\d x} - a b y = 0$

where $a$, $b$ and $c$ are complex numbers.

Also presented as
Some sources present this as:


 * $x \paren {x - 1} \dfrac {\d^2 y} {\d x^2} + \paren {\paren {a + b + 1} x - c} \dfrac {\d y} {\d x} + a b y = 0$

which reduces to the given form on multiplication of all terms by $-1$.
