关于连续随机过程最大值的位置

On the location of the maximum of a continuous stochastic process

Leandro P. R. Pimentel

摘要:

本文给出了区间上随机过程最大值位置唯一的一个充必要条件。结果还将表示位置的平均值,该平均值表示为基本过程的线性扰动的最大值的期望的导数。作为应用,我们将考虑一个具有可变漂移的布朗运动。证明方法背后的思想也将有助于研究最大值的位置,在实数线上,双边布朗运动减去抛物线和平稳过程减去抛物线。

英文摘要:

In this short note we will provide a sufficient and necessary condition to have uniqueness of the location of the maximum of a stochastic process over an interval. The result will also express the mean value of the location in terms of the derivative of the expectation of the maximum of a linear perturbation of the underlying process. As an application, we will consider a Brownian motion with variable drift. The ideas behind the method of proof will also be useful to study the location of the maximum, over the real line, of a two-sided Brownian motion minus a parabola and of a stationary process minus a parabola.
