Abstract:

This paper deals with the following class of nonlocal Schr\"odinger equations $$(-\Delta)^s u + u =
u
^{p-1}u \ \ \text{in} \ \mathbb{R}^N, \quad \text{for} \ s\in (0,1).$$ We prove existence and symmetry results for the solutions $u$ in the fractional Sobolev space $H^s(\mathbb{R}^N)$. Our results are in clear accordance with those for the classical local counterpart, that is when $s=1$.

Keywords: fractional Laplacian, critical Sobolev exponent, fractional Sobolev spaces, Nonlinear problems, spherical solutions, ground states
