  2. 2. On set-valued intertwining duality for diffusion processes
    Laurent Miclo

    Markov intertwinning relations were first developed in the finite state space setting to provide a probabilistic approach to convergence to equilibrium.
    We will see how to adapt this method to diffusions on Riemannian manifolds, through stochastic extensions of mean curvature flows.

  4. 4. On weighted Poincaré inequalities for multivariate Liouville and elliptical distributions - Application to Global Sensitivity Analysis

    In this work, we develop new weighted Poincaré inequalities for two clases of multivariate probability measures: multivariate Liouville and elliptical contoured distributions. The former are established via a radial-type decomposition involving the Dirichlet distribution, while the latter are obtained through their spherical counterparts. We further extend this type of results to measures with...

  18. 18. Active Brownian particles with mean-field interaction: singular interactions and multiple invariant measures
    Oscar de Wit
    22/05/2026 11:45

    We introduce a mean-field McKean-Vlasov model for a collective of ants. The model sustains two non-trivial dynamical behaviours: aggregation and lane formation. We show the well-posedness and mean-field limit for the particle model with singular interactions via a compactness method. We also show the existence of multiple invariant measures via perturbative Fourier-style bifurcation analysis,...
