Abstract

Multi-scales method is used to analyze a nonlinear differential-difference equation. In the order 3 the NLS eq. is found to determine the space-time evolution of the leading amplitude. In the next order this has to satisfy a complex mKdV eq. (the next in the NLS hierarchy) in order to eliminate secular terms. The zero dispersion point case is also analyzed and the relevant equation is a modified NLS eq. with a third order derivative term included.
