[tex]-p(\varphi\frac{d^2\overline{\phi}_n}{d\phi^2}-\acute{p}9\varphi\frac{d\overline{\phi}_n}{d\varphi}+q(\varphi)\overline{\phi}_n=\lambda_nw(\varphi)\overline{\phi}_n(\varphi)[/tex]

I would much rather have a solid good resource so I can study Sturm-Liouville. Ideally one that has a good range of problem sets I can practice with. Particularly since its been over 15 years since I completed University.

However like a lot of things if you don't keep in practice one tends to forget lol

I did some google searching on the topic but would like to know if anyone has any recommendations.
