题目：Asymptotic decay for semilinear wave equation
报告人：杨诗武 助理教授（北京大学）
Abstract：
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 that in space dimension 1 and 2, the solution decays in time with an inverse.
polynomial rate, hence giving an affirmative answer to a conjecture raised by Lindblad and Tao. In higher dimension, we obtain improved scattering results for the solutions. These results are based on vector field method with new multipliers. Part of these works are jointed with Dongyi Wei.
