Ordinary Differential Equations

"A fresh modern approach to the geometric qualitative theory of ordinary differential equations ... suitable for advanced undergraduates and some graduate students. "The notions of vector field, phase space, phase flow, and one parameter groups of transformations dominate the entire presentation. The author is acutely aware of the pitfalls of this abstract approach (e.g., putting the reader to sleep) and does a brilliant job of presenting only the most essential ideas with an easily grasped notation, a minimum formalism, and very careful motivation." - TechnometricsArnold, V.
