Perturbations of a critical fractional equation

Eduardo Colorado, Arturo de Pablo and Urko Sánchez

Vol. 271 (2014), No. 1, 65–85
Abstract

We deal with the following fractional critical problem:

where $\Omega \subset {ℝ}^{N}$ is a regular bounded domain, $0<\alpha <2$ and $N>\alpha$. Under appropriate conditions on the size of $f$, we prove existence and multiplicity of solutions.
