布朗运动上确界过程的积分

The integral of the supremum process of Brownian motion

Svante Janson, Niclas Petersson

摘要:

本文研究标准布朗运动上确界过程的积分。我们给出了时间区间[0,T]中过程所覆盖的积分(或面积)A(T)的矩的显式公式。作为结果,A(T)的拉普拉斯变换如下。主要证明涉及A(T)的双拉普拉斯变换,并基于布朗运动的游程理论和局部时。

英文摘要:

In this paper we study the integral of the supremum process of standard Brownian motion. We present an explicit formula for the moments of the integral (or area) A(T), covered by the process in the time interval [0,T]. The Laplace transform of A(T) follows as a consequence. The main proof involves a double Laplace transform of A(T) and is based on excursion theory and local time for Brownian motion.
