Abstract
The dynamics of the driven and dampedΦ 4 kink exhibits a non-uniform onset of the center-of-kink motion and consequently a corresponding generalized relaxation of its linear modes. The usual uniformly driven regime and linear exponential regimes of the damped oscillations or relaxation of its linear modes set in asymptotically for large times. The related characteristics of the initial regime is the expansion of the kink to the constant width of the asymptotic uniformly driven and damped kink.
