Scattering for the focusing $L^2$ -supercritical and ${\dot{H}}^2$-subcritical biharmonic NLS Equations

Qing Guo

We consider the focusing ${\dot{H}}^{s_c}$-critical biharmonic Schrödinger equation, and prove a global wellposedness and scattering result for the radial data $u_0\in H^2(\mathbb R^N…
