Long Time Energy and Kinetic Energy Conservations of Exponential Integrators for Highly Oscillatory Conservative Systems
《Numerical Mathematics(Theory,Methods and Applications)》2022年第3期620-640,共21页Ting Li Changying Liu Bin Wang 
supported by the Natural Science Foundation of China under Grants 11801280,12071419;the Natural Science Foundation of Jiangsu Province under Grant BK20180780.
In this paper,we investigate the long-time near-conservations of energy and kinetic energy by the widely used exponential integrators to highly oscillatory conservative systems.The modulated Fourier expansions of two ...
