TL;DR: In this article, the main properties of Dirichlet spaces can be proved without the classical local compacity hypothesis, and these results are applied to the Ornstein-Uhlenbeck semi-group on Wiener space, where it is obtained that the real random variables, which are solutions of lipschitzian stochastic differential equations, always have probability densities after perhaps an initial deterministic phase.
