In this paper, we prove scattering for the beam equation with quadratic nonlinear term assuming that the initial data is radial and below some thresholds with the spatial dimensions 8d11. The main difficult part is the so-called mass critical case for d=8. We use the method of Dodson-Murphy [7] without concentration-compactness argument to obtain scattering.

具有径向初始数据的二次梁方程的散射

在本文中,我们证明了具有二次非线性项的光束方程的散射,假设初始数据是径向的并且低于一些具有空间维度的阈值 8d11. 主要的困难部分是所谓的大规模临界案例d=8. 我们使用 Dodson-Murphy [7] 的方法没有浓度 - 紧凑性参数来获得散射。
