Abstract

In this work, we mainly focus on the energy-supercritical nonlinear Schr\"odinger equation, itu+Δu=μupu,(t,x)Rd+1, i\partial_{t}u+\Delta u= \mu|u|^p u, \quad (t,x)\in \mathbb{R}^{d+1}, with μ=±1\mu=\pm1 and p>4d2p>\frac4{d-2}. %In this work, we consider the energy-supercritical cases, that is, p(4d2,+)p\in (\frac4{d-2},+\infty). We prove that for radial initial data with high frequency, if it is outgoing (or incoming) and in rough space Hs1(Rd)H^{s_1}(\mathbb{R}^d) (s1<sc)(s_1<s_c) or its Fourier transform belongs to Ws2,1(Rd)W^{s_2,1}(\mathbb{R}^d) (s2<sc)(s_2<s_c), the corresponding solution is global and scatters forward (or backward) in time. We also construct a class of large global and scattering solutions starting with many bubbles, which are mingled with in the physical space and separate in the frequency space. The analogous results are also valid for the energy-subcritical cases.
