李系统的一种新的几何方法及其物理应用

A new geometric approach to Lie systems and physical applications

José F. Cariñena, Arturo Ramos

摘要:

微分方程系统的特点承认一个叠加功能,使我们能够写的一般解决方案的任何基本的一组特殊的解决方案进行了讨论。这些系统被证明是与李群上的方程和纤维丛中的一些连接。我们开发了两种方法来处理这样的系统:广义魏-诺曼方法和减少的方法,这是非常有用的,当特定的解决方案的原始问题是已知的。这个理论在经典力学和量子力学中都有一些应用。

英文摘要:

The characterization of systems of differential equations admitting a superposition function allowing us to write the general solution in terms of any fundamental set of particular solutions is discussed. These systems are shown to be related with equations on a Lie group and with some connections in fiber bundles. We develop two methods for dealing with such systems: the generalized Wei--Norman method and the reduction method, which is very useful when particular solutions of the original problem are known. The theory is illustrated with some applications in both classical and quantum mechanics.
