TQFT and Knot Theory

mercredi 22 avr. 2026, 13:30 → 17:30 Europe/Paris

Salle Yvette Cauchois (IHP - Bâtiment Perrin)

The Seed seminar of mathematics and physics is a seminar series that aims to foster interactions between mathematicians and theoretical physicists, especially among young researchers. It is structured into three-month thematic periods, the spring 2026 one being on TQFT and Knot Theory.

We open this thematic trimester with an in-person kick-off event at the Institut Henri Poincaré with contributions from Christian Blanchet, Giovanni Rizi and Jules Martel.

Registration for attending the event in person is free but mandatory, see Registration in the indico menu.

If you cannot attend the event in person but are interested in following the talks online, please register here anyway, specifying that you will be participating online when asked. Only those who have registered in this way will receive the Zoom link to participate.
