  • Colin Fourel

    From Morse homology to Floer homology

    21 novembre 2024 - 16:30Salle de conférences IRMA

    Morse homology is a homology theory that allows to say something about the critical points of a smooth function on a manifold. It can be used for example to prove lower bounds on the number of critical points, called the Morse inequalites. Inspired by these, Arnold conjectured a generalization concerning the number of periodic orbits of certain vector fields. I will explain how one gets the Morse inequalites using Morse homology, and how one can prove Arnold conjecture thanks to an infinite dimensional version of Morse theory, called Floer theory.
