In this paper, we consider the nonlinear Schrödinger equation,itu+Δu=μ|u|pu,(t,x)Rd+1, with μ=±1,p>0.

In this work, we consider the mass-subcritical cases, that is, p(0,4d). We prove that under some restrictions on d,p, any radial initial data in the critical space H˙sc(Rd) with compact support, implies global well-posedness.

非线性薛定谔方程 I 的大型全局解,质量亚临界情况

在本文中,我们考虑非线性薛定谔方程,+Δ=μ||,(,×)电阻d+1,μ=±1,>0.

在这项工作中,我们考虑质量亚临界情况,即, (0,4d). 我们证明在一些限制下d,, 临界空间中的任何径向初始数据 H˙(电阻d) 紧致支撑,意味着全局适定性。
