Summary on Grant Application Form 
Stochastic partial differential equations (SPDEs) arise in many physical problems such as neuron sciences, mathematical biology, fluid dynamics, geophysics, plasma physics etc. To understand the long time behaviour of solution is one of the most important problems in random dynamical systems. Invariant manifolds is a useful characterization of the local behaviour. Invariant measures represent the weak convergence of the solution. In this proposal, we propose to study the pathwise convergence and long time behaviour of solutions of SPDEs. Following our recent breakthrough on existence of semiflows of stochastic partial differential equations and stochastic evolution equations (references 11 and 12), the proposed research is to study the pathwise local behaviour of SPDEs near a stationary solution and the global structutre of some more specific SPDEs and stochastic reaction diffusion equations, existence of the stationary solutions, Lyapunov exponents, and extend these results to more SPDEs such as when the noise is of (linear/nonlinear) multiplicative type. We will study the existence of the stationary solutions by studying the integral equations that we have recently observed in reference 12. These are fundamental problems in stochastic dynamical systems. The SPDEs that we proposed to study include some wellknown equations such as stochastic KPP equations, stochastic GinzbarghLandan equation, stochastic ChafeeInfante equations, stochastic Burgers equations and stochastic NavierStokes equations. These equations arised in real physical problems.
