Concentration-compactness principle for nonlocal scalar field equations with critical growth

João Marcos do Ó, Diego Ferraz

The aim of this paper is to study a concentration-compactness principle for homogeneous fractional Sobolev space ${\mathcal{D}}^{s,2}({\mathbb{R}}^N)$ for $0<s<\min \{1,N/2\}.$ As an a…
