SUMMARY:Solitary waves with intrinsic wavelength - Wang\, Z (University Co
 llege London)

DESCRIPTION:A solitary wave is a localized coherent structure that maintai
 ns its shape while it travels at constant speed. Solitary waves are caused
  by a cancellation of nonlinear and dispersive effects in the medium. In t
 his talk\, we discuss a special type of solitary wave: wavepacket solitary
  waves. In contrast to the celebrated KdV soliton\, wavepacket solitary wa
 ves have intrinsic length scale and feature oscillatory decaying tails. Tw
 o examples\, capillary-gravity waves and flexural-gravity waves\, will be 
 presented to illustrate the importance of wavepacket solitary waves\, the 
 numerical methods for constructing these waves and their dynamics.\n
