摘要
本文把现代微分几何的基本概念与方法应用于经典力学,给出一种推导完整系统动力学方程的极为简捷的方法.进而在相空间构造一个向董杨,使其积分曲线为哈密顿方程的解,并导出相流的一些积分不变量。
In this paper, the basic ideas and methods of modern differential geometry are used in classical mechanics. We give a quick method for writing equations of holonomic systems. on phase space we construct vector fields whose integral curves satisfy Hamilton's equations and obtain some integral invariant of a hamiltonian phase flow.
