The equations of motion for the order parameters of a coupled linear chain system in a condensed Peierls phase are derived from a microscopic Hamiltonian. These results now provide the correct non-linear terms which are needed to discuss solitary wave excitation modes. The computation reported here is a mean field result, at T = 0, and with interchain electron backscattering. Amplitude solitary waves are energetically disallowed, but phase solitons (φ-particles) with small associated amplitude variation are possible.
