| Jan 30, 2024 at 2:59 | comment | added | Adam | Thanks a lot for your explanation. I mostly followed what you said. However the equation $d^4x'=\left|\frac{\partial x'^\mu}{\partial x^\nu}\right|d^4x$ seems to contain two independent indices on the right hand side and no indices on the left. How is this possible? | |
