Abstract:We prove the existence of positive solutions to the supercritical nonlinear fractional Schrodinger equation $(-/Delta)^s u+V(x)u-u^p=0 /mbox{ in } R^n$, with $u(x)/to 0$ as $|x|/to +/infty$, where $p>/frac{n+2s}{n-2s}$ for $s/in (0,1), / 2s/frac{n+2s-1}{n-2s-1}$, this problem admits a continuum of solutions.  More generally, for $p>/frac{n+2s}{n-2s}$, conditions for solvability are also provided. This result is the extension of (Davila-Del Pino-Musso-Wei JDE 2007) to the fractional case.  The main contributions for the fractional case are the existence of a smooth, radially symmetric, entire solution of $(-/Delta)^s w=w^p /mbox{ in }R^n$ and the analysis of its properties. The difficulty here is the lack of phase-plane analysis for a nonlocal ODE; instead we use conformal geometry methods together with Schaaf's argument.
