The lectures on 14.10 or 16.10 are cancelled. The first lecture will be on Monday, October 21.October 14 is a welcome day for first-term students. All lectures are cancelled.

The cancellation of the October 16 lecture is due to an administrative problem that prevents the instructor (Dr. Manfred Kufleitner, University of Stuttgart),to start his appointment as invited professor at TUM before the beginning of the term. We apologize for the inconveniences.
