Professor Damien Calaque
Assistant Claudia Scheimbauer, Mathieu Anel
Time Tue 3-5
Place HG G19.2
Requirements Students are required to give one or two talks, depending on the subject and length.
Meetings We will meet once approximately 2 weeks before the talk, usually on Monday afternoons ("office hours") in Damien Calaques office HG G 28.3. Furthermore, you can ask questions to Claudia or Mathieu.
First meeting Tue, Sept. 18, 3-5.
Talks will be distributed at the first meeting! Please contact the organizers beforehand if you are unavailable on this day.

Goal

The ultimate goal for this Seminar is to understand the statement of the cobordism hypothesis after Baez-Dolan and Lurie. This will serve as a pretext for introducing several important notions and concepts from higher category theory and homotopy theory.

Overview of the semester

A detailed outline of the talks can be found here.
