Forward period analysis and the long term simulation of a periodic Hamiltonian system
Pengfei Wang
The period of a Morse oscillator and mathematical pendulum system are obtained, accurate to 100 significant digits, by forward period analysis (FPA). From these results, the long-t…

The finite precision computation and the nonconvergence of difference scheme
Wang Pengfei, Li Jianping
The authors show that the round-off error can break the consistency which is the premise of using the difference equation to replace the original differential equations. We therefo…
