Abstract:

In this paper, we study the symmetry and monotonicity of positive solutions for fractional Laplace equations involving the Hardy potential. Firstly, the Kelvin transform is performed on a certain point, and then we establish a narrow region principle and decay at infinity principle. By using this principle and the moving plane method, the result that the positive solution is symmetric about a certain point and first increases and then decreases is obtained.
