Notable omission from the main article is a biographical reference to the person behind this eponymously named theorem. DFH 20:41, 21 November 2006 (UTC)Reply

Untrue edit

One sentence makes the claim:

"The Van der Pol equation has no exact, analytic solution."

No doubt whoever wrote this meant something like that the solution of the Van der Pol equation cannot be expressed in terms of elementary functions.

But it certainly has an exact analytic solution, where the word analytic means a function that can be expressed at least locally in terms of convergent power series.

I hope someone knowledgeable about this topic can fix this error.
