报告摘要
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 Lindblad and 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.
