內(nèi)容介紹：In this talk, we will introduce the method of moving planes for nonlinear fractional parabolic equations ?_t u+〖(-?)〗^s u=f(t,u(x,t)). We will prove narrow region principles, both asymptotic and for entire solutions. Then we will apply the method of moving planes to prove the radial symmetry and monotonicity of positive solutions to such equations in a unit ball and the monotonicity of solutions on a half space. We will illustrate how to modify the methods and estimates on elliptic problems so that they can be applied to parabolic problems.
