Confluent Hypergeometric Differential Equation

The second-order ordinary differential equation

xy^('')+(c-x)y^'-ay=0,

sometimes also called Kummer's differential equation (Slater 1960, p. 2; Zwillinger 1997, p. 124). It has a regular singular point at 0 and an irregular singularity at infty. The solutions

y=b_1_1F_1(a;c;x)+b_2U(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 Phi(a;c;z).
