Le séminaire a lieu le Lundi
22 janvier 2001 de 14h30 à 15h30
dans la salle de réunion
du PHC (Observatoire de Nice).
The nonlinear propagation of waves of short wavelenght
in dispersive systems will be discussed.
A family of equations will be presented
describing the asymptotic behaviour of a
large class of systems. A particular attention will be
devoted
to the analysis of the simplest nonlinear short-wave
dynamics in the BBMP equation.
