Symmetry results of positive solutions of integral equations involving Riesz potential in exterior domains and in annular domains

摘要

The purpose of this paper is to investigate positive solutions of integral equations involving Riesz potential. Exploiting the moving plane method in integral form, we give the radial symmetry of both the domain and solutions of our integral equations in exterior domains and in annular domains.
