Sturm-Liouville Equation
A second-order Ordinary Differential Equation
where
is a constant and 
is a known function called either the density or Weighting Function. Thesolutions (with appropriate boundary conditions) of are called Eigenvalues and thecorresponding 
Eigenfunctions. The solutions of this equation satisfy importantmathematical properties under appropriate boundary conditions (Arfken 1985).See also Adjoint Operator, Self-Adjoint Operator
