Seminar: The h-Principle, Sommersemester 2025

For information on the topic of the seminar and practical details such as times, location, prerequisites and requirements, see this seminar announcement. I can also recommend this video on the Smale sphere eversion, which is one of the most famous and mind-bending examples of an h-principle result.

That document also contains the enrollment key for the moodle, which you should join if you want to participate.
Note: HU students can access moodle using their HU username and password. Non-HU users can access it by following this link and then clicking on "Create new account".
