Pass Criteria

Solve correctly at least 25% of the assignments. Hand in solution attempts for at least 50% of the assignments. Present a correct solution to an assignment on the blackboard in the recitation session at least once. Pass the written exam.


Students of mathematics or physics, including teachers, from semester 3. Direct access to thesis projects: bachelor, master, dissertation. Students interested in dynamical systems are also welcome to participate in the seminar Geschichte(n) der Dynamik. Please note that topics will be distributed on April 18, 10 a.m. It will be possible to give your talk in English.


Dynamical Systems are concerned with anything that moves. Through the centuries, mathematical approaches take us on a fascinating voyage from origins in celestial mechanics to contemporary struggles between chaos and determinism.

The three semester course, aimed at graduate students in the framework of the Berlin Mathematical School, will be mathematical in emphasis. Talented and advanced undergraduates, however, are also welcome to this demanding course, as are students from the applied fields, who plan to really progress to the heart of the matter.

Here is an outline of the first semester:

Semester 1:

  1. Existence and uniqueness of solutions of ordinary differential equations
  2. Flows, differentiablility and first integrals
  3. Linear differential equations
  4. Omega-limit sets and Lyapunov functions
  5. Planar flows and the Poincaré-Bendixson theorem
  6. Forced oscillations
