"Lorentz invariance stipulates that the laws of physics are the same for all observers, regardless of where they are in the universe. Einstein used this principle as a postulate of special relativity, assuming that the speed of light in a vacuum does not depend on who is measuring it, so long as that person is in an inertial frame of reference. " http://physicsworld.com/cws/article/news/40834 

根据这段话,Lorentz invariance  好像就是爱因斯坦的相对性原理加光速不变。

-----------------------------------

“To begin to understand Kostelecky's work on Lorentz violation it is important to realize that there are actually two ways to view Lorentz symmetry. The statement that the laws of physics are the same for all inertial observers is what is known as Lorentz invariance. This elegant symmetry simply says that nature's laws cannot depend on the perspective of an observer: a person on a moving train and a person waiting at a station, for example, obey the same laws of physics. But what happens if the person on the train gets up and starts to walk about? Giving a particle or object a motion with respect to a fixed inertial frame (the train in this case) is called a Lorentz transformation.” http://www.cfa.harvard.edu/Walsworth/pdf/PhysicsWorld_2004.pdf 

"the symmetry that requires the laws of physics to be the same for all observers is known as Lorentz symmetry."  http://www.cfa.harvard.edu/Walsworth/pdf/PhysicsWorld_2004.pdf 

我不知道怎么区分 Lorentz invariance 和 Lorentz symmetry。

请大家帮帮忙,谢谢。
