Abstract: (Elsevier)

We show that no symmetric three-closed-string vertex can give dual off-shell amplitudes for four-string scattering. This implies that covariant closed string field theory cannot be cubic. We conjecture the necessity of non-polynomiality. Our result implies the uniqueness of the cubic formulation of covariant open string field theory.
