Introducation to Hamiltoian Systems and Symplectic Geometric Method
This course is a brief introduction to Hamiltonian systems and symplectic geometric numerical methods(simply called symplectic methods). The topics include: (1) Basics of Hamiltonian dynamical systems; (2) Stability and KAM theory; (3) Kang Feng’s idea on geometric numerical methods of dynamical systems; (4) Symplectic methods based on Hamilton-Jacobi equations and generating function theory; (5) Symplectic methods based on Runge-Kutta\Patitioned Runge-Kutta methods; (6) Symplectic methods based on the splitting of vector fields and composition of phase flows; (7) Numerical stability; (8) Backward error analysis and almost preservation of invariants
