报告摘要:In this talk, we will first give a survey on the direct methods we introduced in recent years to study nonlinear equations involving pseudo-differential nonlocal operators, such as the direct method of moving planes, moving spheres, and blowing-up and re-scaling. Then we will focus on nonlinear equations involving the fractional p-Laplacian. We prove a maximum principle for anti-symmetric functions and obtain other key ingredients for carrying on the method of moving planes, such as a key boundary estimate lemma. Then we establish radial symmetry and monotonicity for positive solutions to semi-linear equations involving the fractional p-Laplacian in a unit ball and in the whole space. We believe that the methods developed here can be applied to a variety of problems involving nonlinear nonlocal operators.
