报告摘要：In this talk, we shall give an insight on dynamics of stochastic Hamiltonian systems from the perspective of stochastic differential equations and geometric mechanics. The report mainly includes two parts: Firstly, we will present an averaging principle of stochastic (symplectic) Hamiltonian systems with non-Gaussian Levy noise. Secondly, we will introduce a stochastic version of contact Hamiltonian systems whose phase flows preserve contact structures. (This talk is based on some joint works with J. Duan, Y. Chao and Z. Wang.)
