Lorenz规范下Yang-Mills-Higgs和Yang-Mills-Dirac系统的标度临界正则性

On the scaling critical regularity of the Yang-Mills-Higgs and the Yang-Mills-Dirac system in the Lorenz gauge

Seokchang Hong

摘要:

本文研究了Lorenz规范下$(1+3)$维Yang-Mills-Higgs(YMH)和Yang-Mills-Dirac(YMD)系统的定域适定性.由于在(YMH)中存在双线性项,这是一个缺乏零结构,人们可以获得最多的能量空间的适定性。然而,我们通过在角变量中施加额外的加权正则性来获得(YMH)的标度临界正则性。在(YMD)中,为了使耦合系统在时间上持续存在,需要对Dirac旋量施加与Yang-Mills规范势和曲率一样多的角正则性。然后,我们可以证明的标度临界正则性(YMD)使用角正则性,而不是零结构的旋量场。在这种方式下,我们提出了一种方法来攻击的缩放临界正则性(YMH)和(YMD)的同时。这个结果是我们最近对Lorenz规范\cite{hong}中的Yang-Mills系统的研究的一个应用。

英文摘要:

In this paper, we study the local well-posedness of the $(1+3)$-dimensional Yang-Mills-Higgs (YMH) and the Yang-Mills-Dirac (YMD) system in the Lorenz gauge. Since there is some bilinear term in (YMH), which is a lack of null structure, one may obtain the well-posedness at most the energy space. However, we attain the scaling critical regularity of (YMH) by imposing the extra weighted regularity in the angular variables. In (YMD), for the coupled system to persist in time, it is required to impose the angular regularity on the Dirac spinor as much as the Yang-Mills gauge potential and curvature. We can then prove the scaling critical regularity of (YMD) using angular regularity instead of the null structure of the spinor field. In this manner, we present an approach to attack the scaling critical regularity of (YMH) and (YMD) simultaneously. This result is an application of our recent study on the Yang-Mills system in the Lorenz gauge \cite{hong}.
