| Mar 19, 2015 at 21:37 | comment | added | physicist | @G.Bergeron I thought boost transformation should transform just like any two indices tensor. I was wrong I think, as ACuriousMind explained. | |
| Mar 19, 2015 at 18:55 | comment | added | G. Bergeron | You were right, I talked too fast and supposed wrongly another transformation. Yours does preserve length, but I don't understand why you expect the transformed boost to have the same functionnal form as the boost when expressed relative to the new coordinates: it is not the same transformation. | |

| Mar 17, 2015 at 23:07 | comment | added | physicist | @ACuriousMind that's very interesting comment.I was treating a certain Lorentz boost which I can compute, to be a simple tensor of two indices. And so when I transform the coordinates with a certain Jacobean then then the boost matrix should also transform in a similar manner. is my understanding wrong? By the way this is a research question not a homework exercise :) | |
| Mar 17, 2015 at 22:36 | comment | added | user73762 | A transformation that changes the metric only in one spatial dimensions seems strange. If you get a length contraction, I (naively) expect there to be some time dillation, too. | |
| Mar 17, 2015 at 22:34 | comment | added | ACuriousMind♦ | Why do you think the Lorentz boost "transforms" at all? It is, intrinsically, an element of a group, not a vector or tensor on the space, so why should it transform in any way? | |
