摘要: In a space of four dimensions I determine all possible second‐order vector–tensor field equations which are derivable from variational principle, compatible with the notion charge conservation and in agreement Maxwell’s flat space. The general solution to this problem contains Einstein–Maxwell (with cosmological term) as special case.
