This course is followed by the course NTMF060 – Geometrical Methods of Theoretical Physics II.

Information about lectures in fall 2021:

Lectures and practicals were scheduled each Wednesday at 14:00–17:10 in lecture room T2.

Both lectures and practicals were taught in person.

Lectures were recorded. Recordings of lectures are available on a special page, the address of which was sent to enrolled students.

If anyone is interested in watching recordings of the lectures without enrolment, please, contact the lecturer by email.

The lectures were given in English.

The examination was possible both in English or Czech.
