Nonlinear Differential Equations and Dynamical Systems (Universitext)

"A good book for a nice price!" (Monatshefte für Mathematik)

"... for lecture courses that cover the classical theory of nonlinear differential equations associated with Poincaré and Lyapunov and introduce the student to the ideas of bifurcation theory and chaos this is an ideal text ..." (Mathematika)

"The pedagogical style is excellent, consisting typically of an insightful overview followed by theorems, illustrative examples and exercises." (Choice)
