Hello,
so my question is, if for some metric, we have found (somehow) Fμν, and we know that:
Fμν=∂μAν-∂νAμ, how do we find Aν?
I tried solving the differential system after imposing the Lorentz gauge ∂μAμ=0
but still, without some initial guess about which components of A are zero, the system cannot be solved.
Since books give often the potential A instead of F, I suppose there is a way to find it, I just can't figure it out on my own. Is there another equation to make the system determined?
