二维三次Dirac方程的整体解

Global solution to the cubic Dirac equation in two space dimensions

Shijie Dong, Kuijie Li

摘要:

我们感兴趣的是二维空间中质量为$m \in [0, 1]$的三次狄拉克方程,它也被称为Soler模型。我们在高正则性索伯列夫空间中对初始数据足够小的模型进行了深入的研究。首先,我们证明了模型的整体存在性,它是质量均匀的。此外,我们得到了一个统一的逐点衰减结果适用于所有$m \in [0, 1]$。最后,我们证明了三次Dirac方程的线性散射具有显式的散射速度。当质量为$m=0$时,我们可以给出一个改进的逐点衰减结果.

英文摘要:

We are interested in the cubic Dirac equation with mass $m \in [0, 1]$ in two space dimensions, which is also known as the Soler model. We conduct a thorough study on this model with initial data sufficiently small in high regularity Sobolev spaces. First, we show the global existence of the model, which is uniform-in-mass. In addition, we derive a unified pointwise decay result valid for all $m \in [0, 1]$. Last but not least, we prove the cubic Dirac equations scatter linearly with an explicit scattering speed. When the mass $m=0$, we can show an improved pointwise decay result.
