摘要

Stochastic partial differential equations are an important tool in the modelling and analysis of complex random dynamical systems. We present a survey on the semigroup approach to their solution and on the main concepts applied today to analyze them. In particular, we review recent results obtained on the existence of invariant measures, (improved) moment estimates and their support properties, as well as uniqueness results for associated Kolmogorov operators. The survey is complemented with various illustrations and a discussion of those examples that have been essential for the development of the theory.
