Gigliola Staffilani (MIT) to give colloquium at 3:00pm on Wednesday, January 22, 2020, in Eckhart 206

3:00–4:00 pm

Title: The Schrodinger equations as inspiration of beautiful mathematics.

Abstract: In recent years 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, math physics, dynamical systems, probability and symplectic geometry. In this talk I will introduce a variety of results using as model problem the periodic 2D cubic nonlinear Schrodinger equation. I will start by giving the  physical  derivation of the equation starting 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, such as the non-squeezing theorem, that one can obtain once the equation is viewed in the frequency space as an  infinite dimension Hamiltonian system.
