Jun 7, 2020 at 23:45 | comment | added | Alex Trounev | @jojo123456 Probably they just try to solve equation $g_{ik}=\eta _{\mu \nu}e^{\mu}_ie^{\nu}_k$. | |
Jun 7, 2020 at 17:13 | comment | added | user255856 | That's one point which I don't understand. Why do they chose these particular $e^{\mu}$'s? I tried to invert $g_{\mu\nu}$ to make the frame locally Minkowski, but that seems not to be what they mean? | |
Jun 6, 2020 at 20:23 | comment | added | Alex Trounev | Before equation (48) they pointed out that "Any physical measurement by an observer in curved spacetime should be carried out in a local inertial frame, i.e., the observable quantities are the projections of the physical quantities on to the four orthonormal bases $e^{\mu}_0, e^{\mu}_1, e^{\mu}_2,e^{\mu}_3$ carried by the observer. Therefore, the observable EM fields are $F_{\alpha \beta}=F_{\mu \nu}e^{\mu}_{\alpha}e^{\nu}_{\beta}$" | |
Jun 6, 2020 at 20:06 | comment | added | user255856 | $F^{\mu\nu}_{(1)}$ has no definition when I do the expansion. It is the function that I am looking for. At the stage of the expansion just consider it as an expersiion which contains one $h$. If you look at the end result you can see that this makes sense | |
Jun 5, 2020 at 19:13 | comment | added | Stratiev | Where you have defined the expansion of $F^{\mu \nu}$ as an expansion in powers of h, I don't quite understand what you mean, since there is no $h$ multiplying the $F^{\mu \nu}_{(1)}$ term. Is it a power series in $det(h_{\mu \nu})$? | |
