Seminar on functor calculus and higher topos

This is a master students seminar, which means you will take turns to present each topic. You will be meeting with us in the week before your presentation to clarify questions, run the format of the talk you are planning, and/or practice your talk.

More references and information to come. Looking forward to meeting you!

When and where: This seminar will take place on Fridays at 10:00 in SemR 0.003.

Organizers: Félix Loubaton and myself. Don’t hesitate to contact us if you have any questions regarding this seminar.
