N2 - We consider a model consisting of two subsystems with crossing linear dispersion curves, in the case when the coupling between the subsystems is purely nonlinear, so that the crossing does not give rise to a gap in the linear spectrum. We demonstrate that there is a fairly general mechanism precluding the existence of (bright) solitons in systems of this type.
