Hi,

there will be no lectures or exercise classes on the week from February 12 to February 16. There will be the following replacements:

Tuesday Feb 06, 12:15-14:00, CK111: Lecture by prof. Antti Kupiainen on Minlos' theorem.
Tuesday Feb 20, 10:15-12:00, C122: Lecture;
Friday Feb 23, 10:15-12:00, C122: Exercises.

The material covered in the additional lectures will be self-contained and the rest of the course will not depend on it.

Kind regards,
Konstantin.
