Poisson Integrators Based on Splitting Method for Poisson Systems
《Communications in Computational Physics》2022年第9期1129-1155,共27页Beibei Zhu Lun Ji Aiqing Zhu Yifa Tang 
supported by the National Natural Science Foundation of China(Grant Nos.11901564 and 12171466).
We propose Poisson integrators for the numerical integration of separable Poisson systems.We analyze three situations in which Poisson systems are separated in threeways and Poisson integrators can be constructed by u...
