这份报纸涉及光滑(在 Meyer-Watanabe 的意义) Gaussian 随机的地的本地时间。为时间,碰撞本地人时间,和本地的自我交叉预定的本地人的存在和光滑的足够、必要的条件为 Gaussian 随机的域的一个大类被建立,包括部分 Brownian 运动,部分 Brownian 表和时空 Gaussian 噪音驾驶的随机的热方程的解决方案。
This paper is concerned with the smoothness (in the sense of Meyer- Watanabe) of the local times of Gaussian random fields. Sufficient and necessary conditions for the existence and smoothness of the local times, collision local times, and self-intersection local times are established for a large class of Gaussian random fields, including fractional Brownian motions, fractional Brownian sheets and solutions of stochastic heat equations driven by space-time Gaussian noise.
