Carnot群中分式次Laplacian的Harnack不等式

Harnack inequality for fractional sub-Laplacians in Carnot groups

Fausto Ferrari, Bruno Franchi

摘要:

本文证明了Carnot-Carathéodory球上关于Carnot群中次Laplacian的分数幂的不变Harnack不等式.该证明依赖于卡法雷利和西尔维斯特最近引入的一种技术的“抽象”公式。此外,我们还在乘积型Carnot群上给出了一类退化次椭圆方程的泊松核。

英文摘要:

In this paper we prove an invariant Harnack inequality on Carnot-Carathéodory balls for fractional powers of sub-Laplacians in Carnot groups. The proof relies on an "abstract" formulation of a technique recently introduced by Caffarelli and Silvestre. In addition, we write explicitly the Poisson kernel for a class of degenerate subelliptic equations in product-type Carnot groups.
