Maxwell Equations in Tensor Notation

²A^\mu=-\mu_oJ^\mu

Griffith's Introduction to Electrodynamics refers to this 4-vector equation as "the most elegant (and the simplest) formulation of Maxwell's equations." But does this encapsulate the homogeneous Maxwell Equations? I see how the temporal components lead to Gauss' Law, and I'm assuming, though I haven't shown it to myself, that the spatial components lead to the Ampere-Maxwell Law. What about Faraday's Law and the divergence of B?

The other two laws are basically obtained by definition of the E and B fields. For example, by defining B as the curl of a vector potential, it is then divergence-less by definition.

I would say that the "most elegant" way to formulate Maxwell's equations is by using the Faraday tensor (F\equiv dA, where d is the exterior derivative) :

dF=0

d*F=4\pi*J

But this requires a little bit of differential geometry to understand.
