相空间中的Noether定理及其应用
摘要
从修改的哈密顿变分原理出发导出相空间的 Noether 定理
对正则拉氏量系统
分析该系统在相空间中的对称性质
可导出其相应的守恒量
而这种相空间中的对称性质在位形空间中常常又是不呈现出来的.对奇异拉氏量系统
该系统具有 Dirac约束
我们分析了约束系统的对称性质
讨论了 Dirac 猜想是否有效.
Abstract
We have deduced the Noether theorem in phase Space based on modified Hamilton's Variational prineiple.For regular Lagraagian System
Consider the symmetry of the systera in phase space
we can obtain the conservation laws in phase space.This symmetry is not explicit in the configuration space as classical Noether theorem.For singular Lagrangian system
from the symme- try properties of constrained system in phase space
we give the Noether theo- rem of this constrained system and some examples that Dirae's conjecture holds true or not.
