诺特定理 Noether's theorem

(重定向自Noether theorem)

诺特定理是理论物理的中心结果之一,它表达了连续对称性和守恒定律的一一对应。例如,物理定律不随着时间而改变,这表示它们有关于时间的某种对称性。如果我们想象一下,譬如重力的强度每天都有所改变,我们就会违反能量守恒定律,因为我们可以在重力弱的那天把重物举起,然后在重力强的时候放下来,这样就得到了比我们开始输入的能量更多的能量。

诺特定理对于所有基于作用量原理的物理定律是成立的。它得名于20世纪初的数学家埃米·诺特。诺特定理和量子力学深刻相关,因为它仅用经典力学的原理就可以认出和海森堡测不准原理相关的物理量(譬如位置和动量)。

Noether's theorem 诺特定理

(重定向自Noether theorem)
Emmy Noether was an influential German mathematician known for her groundbreaking contributions to abstract algebra and theoretical physics.

Noether's (first) theorem states that every differentiable symmetry of the action of a physical system has a corresponding conservation law. The theorem was proven by German mathematician Emmy Noether in 1915 and published in 1918. The action of a physical system is the integral over time of a Lagrangian function (which may or may not be an integral over space of a Lagrangian density function), from which the system's behavior can be determined by the principle of least action.
