主讲内容:

The aim of this talk is to introduce some classification results of the solutions for the critical nonlocal equations 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.
