摘要

本文研究了时间积分对高斯过程泛函的正则化效应，重点研究了它们的协方差函数。我们研究了几个重要的协方差函数类的例子，以验证它们是否满足正则化的充分条件。此外，我们还得到了平交道口泛函平滑性的一个弱暗示。

Regularization effects of time integration on Gaussian process functionals

In this paper, we investigate the regularization effects, in the sense of Malliavin calculus, on functionals of Gaussian processes induced by time integration, focusing on their covariance functions. We study several examples of important covariance functions classes to verify whether they satisfy the sufficient conditions proposed for regularization. Additionally, we derive a weak implication for the smoothness of level-crossing functionals.
