Apologies- if this is not the correct forum for such questions please.
I am looking for standard texts on following two topics (for self-study)
1. Ordinary Differential Equations (ODE's)
2. Partial Differential Equations (PDE's)
Level - Beginner/Intermediate. Something for an advanced under-grad or beginner's grad course
(Basically something like Rudin/Bartle-Analysis, Artin/Herstien - Algebra etc)
Even if you can point to a site - where I can get this info that would be great.
