Lecture plan

This is the lecture plan for the autumn semester 2021. Lecture 1-13 will consist of a 2h lecture in A1-040 (Fri 08-10) + 1h video lecture (Fri 11-12).
Office hours: Thu 1400-1600 at my office B4-032. I have an open door policy, which means that you may come to my office at other times (no appointment needed).
Plenary sessions: Mon 1700-1945 (four sessions). In plenary sessions, I will solve selected problems. See the lecture plan below for details.
Exercise sessions: Mon 1700-1845 (weekly). In exercise sessions, you will work with problems, and teaching assistants will be available to help. See the lecture plan below for details.
