Course of Action and Topics of the Lecture Part

Attention: This semester, the course is planned to be held as a mixed presence/online course, with a possible fall-back to a pure online course depending on the COVID situation. The final exam is oral and also depending on the situation, it will be held in presence or online. Moreover, the exercise test is in written form and also for that the COVID situation will determine whether it will be held in presence or online form.
