摘要

对于对称Levy过程，如果局部时间存在，Tanaka公式已经通过Salminen和Yor 2007的势理论中的技术构造出来。本文在Ito随机微积分的框架下，研究了指数α∈1,2的任意严格稳定过程的Tanaka公式，包括谱正和谱负情况。我们对这类进程是否存在当地时间的看法不同于1996年贝尔托的看法。

Tanaka formula for strictly stable processes

For symmetric Levy processes, if the local times exist, the Tanaka formula has already been constructed via the techniques in the potential theory by Salminen and Yor 2007. In this paper, we study the Tanaka formula for arbitrary strictly stable processes with index α ∈ 1, 2, including spectrally positive and negative cases in a framework of Ito’s stochastic calculus. Our approach to the existence of local times for such processes is different from that of Bertoin 1996.
