Resumen:

We discuss the derivation of PDEs as limits as N tends to infinity of the dynamics of N points for a certain class of  Coulomb and Riesz-type singular pair interactions. The method is based on studying the time evolution of a certain "modulated energy" and on proving a functional inequality relating certain "commutators" to the modulated energy. When additive noise is added, some uniform in time convergence  results can be obtained.  Based on joint works with Hung Nguyen, Matthew Rosenzweig, Antonin Chodron de Courcel.
