Lorentz Transformation: Conservation of Inner Product?

Click For Summary
SUMMARY

The discussion centers on the Lorentz transformation as a specific type of coordinate transformation in the context of special relativity. It emphasizes that the conservation of the inner product is a fundamental property of Lorentz transformations, which are linear transformations. The participants argue that while the vector transforms in one way, the metric transforms inversely, ensuring the inner product remains unchanged. This leads to the conclusion that not all coordinate transformations qualify as Lorentz transformations, as they must adhere to linearity.

Is Lorentz transformation one kind of coordinate transformation? If so, the conservation of inner product, which is the primary property of Lorentz Transformation, is trivial, isn't it? The vector transforms in some way, the metric transforms in the inverse way, so the inner product defintely will not change under a coordinate transformation. If so, any coordinate transformation can be Lorentz transformation?

The transformation must be linear as well.
