Lectures

Lectures take place on Mon 10:15-12:00 at HG G 5 and Wed 11:15-12:00 at HG F 5 .

Lectures and classes will not take place during Easter week from Friday, 07.04.2023 to Sunday, 16.04.2023.

Recordings of the lectures are available here .

Lecture Notes

Lecture notes are provided as ipython notebooks or in form of slides as well as of classical notes.

Exercise classes

Exercises will be available in the exercise class. Students are expected to voluntarily do calculations and present results in class. Solutions will also be released right during the exercise class.
