利用热核高斯估计及其相关性质,研究了严格局部正则Dirichlet形式下Hunt过程样本轨道的内在正则性。我们描述了这些结果如何专门用于黎曼布朗运动和次椭圆对称扩散。
Using heat kernel Gaussian estimates and related properties, we study the intrinsic regularity of the sample paths of the Hunt process associated to a strictly local regular Dirichlet form. We describe how the results specialize to Riemannian Brownian motion and to sub-elliptic symmetric diffusions.
