英文摘要: Infinite-dimensional random dynamical systems is now an important and hot topics in the field of international dynamical systems. This project will mainly study the following several problems concerning the attractor of infinite-dimensional random dynamical systems: the dimensional estimate of random attractor, construction of random exponential attractor and establishing some new theoretical results and methods; the random attractors and their geometric properties for the stochastic evolution equations driven by fractional Brownian motion and non-Gauss stochastic processes; and the random attractors of stochastic lattice systems and stochastic wave equations; the structure of the trajectories on the random attractors. The realization of this project will enrich the theory of random dynamical systems and applications.
