The vector potential in any gauge is expressed as the retarded potential plus a gradient built from the scalar potential, which reduces to the known gauge transformation from the Lorenz gauge.

abstract
Heras purports to show without solving the requisite dynamic equations how the non-causal term generated by the scalar potential of the Coulomb, Kirchhoff, or velocity gauge is canceled by an equal and opposite term in the contribution to the electric field that is generated by the vector potential. Heras's procedure is criticized as being just an algebraic manipulation that has no explanatory content.

Direct, analytic solution for the electromagnetic vector potential in any gauge
