报告摘要：The aim of this talk is to introduce some classification results of the solutions of the critical nonlocal equation with weighted nonlocal term and the subcritical case of the form The critical exponent is due to the weighted Hardy-Littlewood-Sobolev inequality and Sobolev imbedding.We prove the existence of positive ground state solutions for the subcritical case by using Schwarz symmetrization and the critical case by a nonlocal version of concentration-compactness principle. We also establish the regularity of positive solutions for these two equations. Finally, we prove the symmetry of positive solutions by the moving plane method in integral forms. Some nondegeneracy results are also established.
