Abstract
We investigate the influence of dispersion on parametric solitary waves. We show that dispersion is responsible for a transition towards a new type of dynamical solitary wave characterized by the presence of traveling phase d efect arrays within their envelopes. The transition is described analytical ly through an original extension of the Kolmogorov-Petrovskii-Piskunov appr oach to front propagation into unstable states.
