Initial Value, Boundary Value, and Eigenvalue Problems   (continued)                                      

 

 

In a Nut Shell:  An eigenvalue problem is special type of boundary value problem

(endpoint problem) with an unknown parameter,   λ , where the differential equation

has the following form along with the associated boundary conditions:

 

 

 

Type 3:   An eigenvalue problem

 

                  y ’’   +   p(x) y ’  +    λ q(x) y   =    0

 

                  y(a)  =  A,    y(b)  =  B

 

where    λ  is a parameter,  the eigenvalues,  yet to be determined.

 

( The goal is to find values of  λ  that yield nontrivial solutions of the d.e. )

 

 

 

 

More general eigenvalue problems take on the following form: 

 

 Involves more complicated expressions for the boundary value

 (endpoint) conditions.

 

 

            y ’’   +   p(x) y ’  +    λ q(x) y   =    0

 

            a1 y(a)    +    a2 y ’(a)   =   0

 

            b1 y(b)   +    b2 y ’(b)   =   0
