# 5: Eigenvalue problems


• 5.1: Sturm-Liouville problems
A classical ”’Sturm-Liouville equation”’, is a real second-order linear differential equation. In the simplest of cases all coefficients are continuous on the finite closed interval [a, b], and p(x) has continuous derivative.
• 5.2: Application of Eigenfunction Series
The eigenfunction series can arise even from higher order equations.
