Intendierte Lernergebnisse
After attending this class students are familiar with the basic concepts of dynamical bifurcation theory. They understand the behavior of differential and difference equations under parameter variations. Note that the class will be elementary and does NOT require previous knowledge on Dynamical Systems.

Erwartete Vorkenntnisse
The course covers elementary topics and therefore only relies on Analysis 1--2, Linear Algebra (Jordan canonical form) and Ordinary Differential Equations. Preliminaries on Dynamical Systems are NOT required.
