Il prossimo SISSA Colloquium si terrà in diretta su Zoom Giovedì 10 Giugno alle 16, con Gigliola Staffilani, Abby Rockefeller Mauze Professor at MIT.
Abstract: In the last two decades great progress has been made in the study of dispersive and wave equations. Over the years the toolbox used in order to attack highly nontrivial problems related to these equations has developed to include a collection of techniques: Fourier and harmonic analysis, analytic number theory, mathematical physics, dynamical systems, probability and symplectic geometry. In this talk I will introduce a variety of results using as a model problem mainly the periodic 2D cubic nonlinear Schrödinger equation. I will start by giving a physical derivation of the equation from a quantum many-particles system, I will introduce periodic Strichartz estimates along with some remarkable connections to analytic number theory, I will move on the concept of energy transfer and its connection to dynamical systems, and I will end with some results on the derivation of a wave kinetic equation.
