Existence of positive solutions for fractional Laplacian systems with critical growth

Jeziel N. Correia, Claudionei P. Oliveira

Abstract:
In this article, we show the existence of positive solution to the nonlocal system

We also prove a global compactness result for the associated energy functional similar to that due to Struwe in [26]. The basic tools are some information from a limit system with a(x) = b(x) = 0, a variant of the Lion's principle of concentration and compactness for fractional systems, and Brouwer degree theory.
