主要内容：

In this talk,we review recent developments of existence-uniqueness and exponential estimate of the pathwise mild solution of retarded stochastic evolution systems driven by a Hilbert-valued Brownian motion.In particularly,the existence-uniqueness of the global pathwise mild solution are given by establishing an integral comparison principle,which extends a classical Pazy theorem on PDEs and the Wintner theorem on ODEs.On the other hand,an exponential estimate for the pathwise mild solution is obtained by constructing a delay integral inequality.The results obtained are applied to a retarded stochastic infinite system and a stochastic partial functional differential equation.Combining some known results,a random attractor is given,whose condition overcome the disadvantage in existing results that the exponential converging rate is restricted by the maximal admissible value for the time delay.
