报告题目: Asymptotic decay for some defocusing nonlinear wave equations

报告人：杨诗武副教授

报告时间：2024.04.01 16:00-17:00pm

讲座地点：汇文楼1420

报告内容：In this talk, I will report recent progress on global behaviors for solutions of energy subcritical defocusing semilinear wave equations with pure power nonlinearity. We prove various type of decay estimates for the solutions in Minkowski space for all space dimensions.  In particular we solve a conjecture of T. Tao in dimension one.  We also extend similar results to the Schwarzschild black hole spacetimes and to the Chern-Simons-Higgs equations in planar physics. These are based on joint works with H. Mei and D. Wei.
