Séminaire Doctorants

organisé par l'équipe DOCT

  • Antoine Rodrigues

    An introduction to Floer theory via classical mechanics

    12 mars 2026 - 16:30Salle de conférences IRMA

    Hamiltonian mechanics on symplectic manifolds can be seen as a general setting for physical problems in classical mechanics. The goal of this talk is to present this setting and show how Floer homology appears as a natural construction to answer dynamical questions. If the time allows it, we will present an application of this general theory to the research of periodic trajectories on a given energy level.

  • Pierre Charitat

    Inferring the brain structure by observing its neurons

    19 mars 2026 - 16:30Salle de conférences IRMA

    Neurophysiologists are able to observe the activity of individual neurons, known as their "spikes". However, this can only be performed for a small amount of neurons, compared to the real size of the network. The goal of this talk is to present a new approach that can estimate the connection proportion between neurons, from the observation of few neurons. We then compare this new approach on a toy model to the actual method generally used by neurophysiologists.
