高阶力学:变分原理及其他

Higher-order Mechanics: Variational Principles and other topics

Pedro D. Prieto-Martínez, Narciso Román-Roy

摘要:

在回顾了高阶(非自治)动力学系统的Lagrangian-Hamilton统一形式(即Skinner-Rusk形式)之后,我们提出了一个统一的几何形式的变分原理,它允许我们导出这类系统的Lagrangian和Hamilton方程。然后,这些原则和相应的动力学方程的标准拉格朗日和哈密顿公式恢复从这个统一的框架。

英文摘要:

After reviewing the Lagrangian-Hamiltonian unified formalism (i.e, the Skinner-Rusk formalism) for higher-order (non-autonomous) dynamical systems, we state a unified geometrical version of the Variational Principles which allows us to derive the Lagrangian and Hamiltonian equations for these kinds of systems. Then, the standard Lagrangian and Hamiltonian formulations of these principles and the corresponding dynamical equations are recovered from this unified framework.
