This project will focus on the construction and analysis of stochastic multi-symplectic geometric algorithm of stochastic Hamiltonian PDEs. The main research topics include, investigating the construction of novel stochastic multi-symplectic geometric algorithm of stochastic Hamiltonian PDEs by using wavelet collocation method and local discontinuous Galerkin method, respectively; doing the theoretical analysis of stochastic multi-symplectic geometric algorithm, including strong (weak) convergence, stability and structure-preserving etc. The research works of this project will solve some important theoretical problems of stochastic multi-symplectic geometry algorithm and provide a practical and efficient method for the numerically solving of the stochastic Hamiltonian PDEs. It has the important theoretical significance and application value.
