稳定过程的迹估计
Trace Estimates for Stable Processes
摘要:
本文研究了$\Rd$中对称稳定过程所对应的热半群的迹(分拆函数)的时间行为。特别是,我们表明,域与所谓的{ \it{$R$-smoothness} }属性的第二项中的渐近作为$t\to 0$涉及域的表面积,就像在布朗运动的情况下。
英文摘要:
In this paper we study the behaviour in time of the trace (the partition function) of the heat semigroup associated with symmetric stable processes in domains of $\Rd$. In particular, we show that for domains with the so called {\it{$R$-smoothness}} property the second terms in the asymptotic as $t\to 0$ involves the surface area of the domain, just as in the case of Brownian motion.
