| Feb 21 at 20:45 | comment | added | octonion | There is a metric in the first line of your question. The issue is whether the d'Alembert operator (in Cartesian coordinates in flat space) reduces to $\partial_t^2 - \partial_x^2$ or $-\partial_t^2 + \partial_x^2$. When you see someone using $-m^2$ they have the second definition in mind. | |
| Feb 21 at 20:39 | comment | added | DrD | Thanks for your answer, octonion. I had already considered that option, but I haven't had to specify any metric in my derivation. So I am not convinced yet. | |
