M ORDER CONTINUOUS FINITE ELEMENT METHODS FOR LINEAR HAMILTON SYSTEMS
【摘要】 <正>1引言哈密尔顿系统是一个重要的动力系统,因此如何正确计算哈密尔顿系统有着重要的意义.正确的计算方法离散后应该保持着问题原型的基本特征.其中辛性质和能量守恒是哈密尔顿系统的两个重要特征.冯康和他的研究小组提出了哈密尔顿系统辛几何算法,
【Abstract】 By applying the continuous finite element methods for ordinary differential equations,the m order finite element methods for linear Hamiltonian systems are proved to be sympiectic as well as energy conservative.The method conserves the energy for nonlinear Hamiltonian systems,too.The numerical results given in the present paper agree with the theory.
