发展p-Laplace方程的平方函数估计

Square function estimates for the evolutionary p-Laplace equation

Kaj Nyström

摘要:

我们证明了新的(本地)平方函数/Carleson措施估计的非负解的发展$p$ -Laplace方程的补充抛物Ahlfors-David正则集。在热方程的情况下,拉普拉斯方程以及$p$ -拉普拉斯方程,相应的平方函数估计已被证明是基本的对称性和反/自由边界型问题,特别是在研究(抛物)一致可求长。虽然平方函数估计的影响是不太清楚的发展$p$ -拉普拉斯方程,主要是由于其缺乏同质性,我们给了一些初步的应用,抛物均匀可求长性,边界行为和Fatou型定理$\nabla_Xu$。

英文摘要:

We prove novel (local) square function/Carleson measure estimates for non-negative solutions to the evolutionary $p$-Laplace equation in the complement of parabolic Ahlfors-David regular sets. In the case of the heat equation, the Laplace equation as well as the $p$-Laplace equation, the corresponding square function estimates have proven fundamental in symmetry and inverse/free boundary type problems, and in particular in the study of (parabolic) uniform rectifiability. Though the implications of the square function estimates are less clear for the evolutionary $p$-Laplace equation, mainly due its lack of homogeneity, we give some initial applications to parabolic uniform rectifiability, boundary behaviour and Fatou type theorems for $\nabla_Xu$.
