Timetable:
Lectures and problem sessions (werkcolleges) are mixed, on most Tuesdays at 9:00 - 10:45 and Thursdays 13:30 - 15:15 in room H226. There are exceptions so please check below for possible room and time changes. The problem sessions are interactive. The material covered in the problems constitutes an essential part of the programme.Office hours: to be determined directly with the students
