They are called (four-dimensional) equations of motion, kind of
generalization of the Heisenberg equation to the spatial components.

So in:
d^uA^v = i[p^u,A^v] with u,v=0,1,2,3
is the p^u = (p^0, p^1, p^2, p^3) a sort of hybrid four-vector, in which the
p^0 = H component is the Hamiltonian and the p^1, p^2, p^3 spatial components
are ordinary three-momentum?
