Oscillon formation as an initial pattern state. Academic Article uri icon

abstract

  • Following Venkataramani and Ott @Phys. Rev. Lett. 80, 3495 ~1998!#, we consider oscillons ~local excitations! as spatiotemporal subcritical bifurcation phenomena. We show in a series of numerical experiments that the appearance of oscillons is highly dependent on the initial pattern state. This finding has led to a new patterning mechanism. In this Brief Report we describe the instabilities that govern the mutual interaction of oscillons/extended patterns. @S1063-651X~99!01011-9#
