Seminar Info

Each session consists of two lectures: an introductory colloquium and a related seminar on a recent advance in geometry. Not all the talks concern scalar curvature but perhaps many do. The pair of talks is followed by a discussion both in person and online. Everyone is welcome to join the session live (zoom) or watch the recorded videos of the talks later (IHES channel).
