Collective coordinates for the hybrid model

In this work, we investigate the soliton scattering problem for anti-kink/kink and kink/anti-kink configurations. To end, employ two distinct methods, full simulation collective coordinates, compare them. We apply coordinate approximation method to describe both configurations in hybrid model show that, similar polynomial models [Formula: see text] text], has limitations with respect initial velocities. such a way certain velocities, solution of coordinates agrees simulation, other there is discrepancy solutions obtained by these methods. time evolution model, taking into consideration null-vector problem. As an appendix, performed same inspection model.
