开集中相对论稳定过程的精确热核估计

Sharp heat kernel estimates for relativistic stable processes in open sets

Zhen-Qing Chen, Panki Kim, Renming Song

摘要:

在本文中,我们建立了相对论稳定过程跃迁密度的精确双边估计[即,对于算子$m-(m^{2/α}-Δ)^{α/2}$ ]在$C^{1,1}$开集中的热核.这里是$m>0$和$α\in(0,2)$。对于每个固定的$M>0$,估计值在$m\in(0,M]$中是一致的。利用$m\downarrow0$,我们恢复了文献[14]中得到的$Δ^{α/2}:=-(-Δ)^{α/2}$在$C^{1,1}$开集中的Dirichlet热核估计.对于有界$C^{1,1}$开集上的相对论稳定过程的格林函数,也得到了精确的双边估计。

英文摘要:

In this paper, we establish sharp two-sided estimates for the transition densities of relativistic stable processes [i.e., for the heat kernels of the operators $m-(m^{2/α}-Δ)^{α/2}$] in $C^{1,1}$ open sets. Here $m>0$ and $α\in(0,2)$. The estimates are uniform in $m\in(0,M]$ for each fixed $M>0$. Letting $m\downarrow0$, we recover the Dirichlet heat kernel estimates for $Δ^{α/2}:=-(-Δ)^{α/2}$ in $C^{1,1}$ open sets obtained in [14]. Sharp two-sided estimates are also obtained for Green functions of relativistic stable processes in bounded $C^{1,1}$ open sets.
