摘要
In this article, we are interested in a fractional Laplacian system in R-N, which involves critical Sobolev-type nonlinearities and critical Hardy-Sobolev-type nonlinearities. By using variational methods, we investigate the extremals of the corresponding best fractional Hardy-Sobolev constant and establish the existence of solutions. To our best knowledge, our main results are new in the study of the fractional Laplacian system.
