Does anyone know a good reference for the constructions of a Greens functions fur the Sturm-Liouville Boundary Value Problem.



Good reference for the construction of a Greens functions fur the Sturm-Liouville
My choice would be **Boundary Value Problems and Green's Functions** by Ivar Stakgold. It have an introduction to *distribution theory* and them apply it to finding Green's functions.


It includes:


* ODE
* PDE with initial conditions
* PDE with boundary conditions.


I found a preview [here](http://cam.ucsd.edu/~mholst/pubs/dist/StHo2011a-preview.pdf)


Cheers
