Frobenius series

First off, this is a great link! Thanks for posting!

Second, I'm working on Power Series Methods, Frobenius series, etc., and I'm looking for any help/links on that. I didn't see any on Paul's site. Might be hidden or is there another site that would cover these topics?

Thanks!

Ordinary Differential Equations and Dynamical Systems

I noticed this link in the bottom of one Wikipedia page about Floquet's theorem:

It's the MIT course website for ODE.

The link for the Honours ODE course is this one:

The MIT http://ocw.mit.edu/OcwWeb/web/courses/courses/index.htm" is a great resource for free online course materials for ALL the undergrad courses they offer.
