The N-wave interaction (NWI) system appears as an amplitude system in
the description of N nonlinearly interacting and linearly transported
wave packets in dispersive wave systems such as the water wave problem
or problems in nonlinear optics. The purpose of this paper is twofold.
First we give a new simplified proof for the failure of the NWI
approximation in case of resonances which are located at integer
multiples of a basic wave number k(0) in the original 2 pi/k0-spatially
periodic dispersive wave system. Secondly, we give a first rigorous
proof that an amplitude system fails in the description of an original
system, without imposing periodic boundary conditions on the original
system.
