We study systems with a time-evolution. This can be continuous (systems of ordinary differential equations in n-dimensional space) or discrete (iterated maps). We begin with discrete dynamical systems.

The theory of dynamical systems analyses the long time behavior (equilibria, periodic points, stability, chaos, ...). We study structural stability of the system under perturbations as well as bifurcations (qualitative changes of behavior) when parameters are varied.

Some more keywords:
Symbolic dynamics, Bernoulli-shift, hyperbolic invariant set, attractor, homoclinic point, and - if time permits - shadowing lemma, Melnikov's theorem.

Numerical simulations will be used to visualize the phenomena.

For Students of Mathematics, Physics, ... , 5th semester or higher

Prerequisits: Linear algebra, multidimensional analysis, basics of ODE.

Due to the wide range of possible topics the detailed selection of the material to be covered can be adjusted to the prerequisits and interests of the audience.
