报告题目：On Symplectic Approximations for Klein--Gordon Equations

报告摘要：The objective of this talk is the symplectic approximation for KG equations. We begin with the formulation of the KG equation as an abstract second-order Hamiltonian system. We then present the symplectic conditions for the approximation, and design symplectic approximation schemes for the KG equation. We finally commence the nonlinear stability and convergence analysis for the symplectic approximation.
