소개 및 안내사항Content | Title : Nonlinear dispersive PDEs, and their applications to mathematical physics.Abstract : The field of nonlinear dispersive PDEs has developed rapidly over last two decades. On the one hand, more refined description of dynamics of solutions, e.g., scattering and blow-up, is discovered toward the soliton resolution conjecture. On the other hand, the techniques from dispersive PDEs have been successfully applied to the problems arising in mathematical physics. In this talk, focusing on the latter aspect, I present recent progress and my research plan in quantum many-body problems and various limit problems, in particular: (1) rigorous derivation of the nonlinear Schrödinger equation from the linear equation; (2) Strichartz estimates and the kinetic energy inequality for orthogonal functions, and their applications to the quantum Landau damping; (3) the semi-classical limit of the quantum Landau damping. If time permits, I will also mention the joint work with Woocheol Choi and Jinmyoung Seok on limit problems along ground states. |
