Title: Morse theory and Poincaré conjecture
Speaker: Enric Solé Farré
Abstract: I will introduce the notion of cobordism and explain how Morse functions extend to them. I will then give a brief sketch of the h-cobordism theorem, its limitations and explain how the Poincaré conjecture follows for n≥5 almost immedately. Time permiting, I will discuss the status of n=4.
Note the unusual location: we are in the basement this week, room 130.
Some snacks will be provided before and after the talk.
This talk will be broadcasted via Zoom. Subscribe to the mailing list or contact organisers to get the Zoom details.
