Abstract:

Using the perturbation method, we constructed the Green’s function for second order linear differential equations associated to a multipoint boundary condition. Moreover, we presented a sufficient condition for the positiveness of the Green’s function.

Key words: Green’s function, positiveness, multipoint boundary value problems, second order differential equation
