Confluent Hypergeometric Differential Equation
Alternate name
Definition
The second-order ordinary differential equation x y'' + (c - x) y' - a y = 0, sometimes also called Kummer's differential equation. It has a regular singular point at 0 and an irregular singularity at ∞. The solutions y = b_1 _1 F_1(a;c;x) + b_2 U(a, c, x) are called confluent hypergeometric function of the first and second kinds, respectively. Note that the confluent hypergeometric function of the first kind is also denoted M(a, c, x) or Φ(a;c;z).
