Abstract
In this paper, narrow region principle for cooperative systems involving fractional Laplacian is developed. As an application, some Liouville type results of the fractional Lane–Emden system(1)
are obtained via the method of moving planes. Different to the conventional method by studying the equivalent integral system, we work directly on the differential system. Our method can also be employed to obtain Liouville type results for general cooperative systems involving fractional Laplacian.
