## Ordinary Differential Equations

and

Dynamical Systems

### Gerald Teschl

Then we establish the Frobenius method for linear equations in the complex domain and investigate Sturm-Liouville type boundary value problems including oscillation theory.

Next we introduce the concept of a dynamical system and discuss stability including the stable manifold and the Hartman-Grobman theorem for both continuous and discrete systems.

We prove the Poincare-Bendixson theorem and investigate several examples of planar systems from classical mechanics, ecology, and electrical engineering. Moreover, attractors, Hamiltonian systems, the KAM theorem, and periodic solutions are discussed as well.

Finally, there is an introduction to chaos. Beginning with the basics for iterated interval maps and ending with the Smale-Birkhoff theorem and the Melnikov method for homoclinic orbits.

A chinese translation has been published by China Machine Press (ISBN 78-7-111-32710-3).

The chinese edition is available as pdf (6.5M) version.
In addition, there is a notebook (1M)
with the Mathematica code from the
text plus some further extensions. To solve complex equations via the
power series method you also need my package
