nLab Heun equation

Heun equation is a second order linear ordinary differential equation of Fuchsian type with 4 regular singular points at 0,1,a,0,1,a,\infty. Its normalized holomorphic solution is the Heun function. If some of the singular points coalesce we talk about the confluent Heun equation.

An application of monodromy analysis of Heun equation (coming from separation of variables) to the physics of black holes:
