Image
Sturm - Liouville Problem:   The Sturm - Liouville Problem is a special class of linear homogeneous boundary value problem given in the following definition.  Definition :      Consider a second order homogeneous linear differential equation of the form   d/dx [p(x) dy/dx ] + [q(x) + λ γ(x)]y=0, a≤x≤b                                                          ...............(1)   where p, q and γ are real - valued continuous functions on [a,b] and λ  is real parameter . Further consider the following two sets of prescribed conditions        a1 y(a) + a2 y'(a) = 0}                                            }...................(2)   ...
