Ciclo de Charlas Explorando la complejidad de las enfermedades infecciosas ¿Qué es un Modelo matemático para el SARS-CoV-2?
Dynamics of unipotent frame flows on hyperbolic manifolds.
ABSTRACT: Joint work with B. Schapira. After explaining the geometry of the objects, we give another proof of a theorem of A. Mohammadi and H. Oh about the ergodicity of the Burger-Roblin measure for Kleinian groups of high enough critical exponents, and relate it with a topological counterpart.

Absence of eigenvalues of Schrödinger, Dirac and Pauli Hamiltonians via the method of multipliers.
Abstract: Originally arisen to understand characterizing properties connected with dispersive phenomena, in the last decades the method of multipliers has been recognized as a useful tool in Spectral Theory, in particular in connection with proof of absence of point spectrum for both self-adjoint and non self-adjoint operators. In this seminar we will see the developments of the method reviewing some recent results concerning self-adjoint and non self-adjoint Schrödinger operators in different settings, specifically both when the...
Non-bijective scaling limit of maps via restrictions.
Abstract: In recent years, scaling limits of random planar maps have been the subject of a lot of attention. So far, the convergence of these random combinatorial objects relies heavily on bijections. In this talk, I will present a non-bijective technique that allows to obtain the convergence of a random map model, using a convergent closely related random map model. Then, I will present a new result which is obtained using our technique: the Brownian disk is the limit of quadrangulations with a simple boundary, when the boundary is of order...
Quantum Mean Field Asymptotics and Multiscale Analysis
Abstract: In a joint work with Z. Ammari, and F. Nier, we study how multiscale analysis and quantum mean field asymptotics can be brought together. In particular we study when a sequence of one-particle density matrices has a limit with two components: one classical and one quantum. The introduction of “separating quantization for a family” provides a simple criterion to check when those two types of limit are well separated. We also give examples of explicit computations of such limits, and how to check that the separating...
