| Apr 13, 2017 at 7:46 | comment | added | Maxim | @SolenodonParadoxus This isn't really an explanation: so $(J_{\alpha \beta})_{\mu \nu}$ are still some kind of differential operators, but $\Lambda^{\mu}_{\;\;\nu}$ is some kind of matrix? How does $\exp$ convert between these? | |

| Apr 13, 2017 at 7:42 | comment | added | Danijel | @SolenodonParadoxus You should also define $[J_{\alpha\beta}]^\mu{}_\nu$ for a more complete explanation. | |
| Apr 13, 2017 at 7:40 | comment | added | Prof. Legolasov | $\Lambda^{\mu}_{\;\nu} = \exp \left( \frac{i}{2} \Omega^{\alpha \beta} \left[ J_{\alpha \beta} \right] ^{\mu} _{\;\nu} \right)$ where $\exp$ is matrix exponential and $\Omega^{\alpha \beta}$ is a collection of 6 parameters (antisymmetric tensor) describing the concrete Lorentz transformation. | |
