| Mar 28, 2018 at 21:36 | comment | added | enumaris | So my answer is wrong or missing something? You are free to provide a better answer yourself. | |
| Mar 28, 2018 at 21:27 | comment | added | freecharly | @enumeraris - The OP is asking about the the value of functions. Also, SR posits the invariance of physical laws in inertial systems. | |
| Mar 28, 2018 at 19:42 | comment | added | enumaris | Hence why I said "generally". And I also specified that the meaning of the word "invariant" is dependent on context. I'm not sure what your point is here. My answer should not serve as a reference to all possible uses of "invariance" in physics, but only to the use that is relevant to the OP's question. | |
| Mar 28, 2018 at 19:24 | comment | added | freecharly | What about "invariance" of the Lagrange function upon generalized coordinate transformations, or the Hamilton function upon canonical transformations? They do no seem to be "tensors". | |
