	I would like to know if anyone has information 
	dealing with the definition of group velocity in
	nonlinear NON-DISPERSIVE media?         

	I have only seen it definied in DISPERSIVE media.
	Are they somehow related - the idea of group velocity
	can only exist in dispersive media?

	Thanks,
	Hema
