报告摘要:This paper is concerned with the smoothness (in the sense of Meyer-Watanabe) of the local times of space-time anisotropic 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 anisotropic Gaussian random fields, including fractional Brownian motions, fractional Brownian sheets and solutions of stochastic heat equations driven by space-time Gaussian noise.
