About the lecture

Time and place

Thursday 16 - 18 c.t. Theresienstr. 37 in A249

Professors: Hartmut Ruhl, Armin Scrinzi

Initial meeting: Thursday, April 19

The general field of the topics is described further down. You are encouraged to find something related to this topics yourself. If you do not so, further concrete topics will be provided in the initial meeting.

Introduction, schedule, and selected topics

Most topics can be treated more analytically or more computationally / numerically, depending on your preferences. You can do literature work, analytical work, or write functioning codes.

Schedule:

The dates and times are still subject to change. We can have one or two presentations per slot!
