Radial Symmetry and Monotonicity of Solutions to a System Involving Fractional p-Laplacian in a Ball

In this paper, we study a nonlinear system involving the fractional p-Laplacian in a unit ball and establish the radial symmetry and monotonicity of its positive solutions. By using the direct method of moving planes, we prove the following result. For 0<s,t<1,p>0, if u and v satisfy the fo...
