1 Lecture 1: Aspects of NLS
1.1 Appearance of NLS (Nonlinear Schrödinger equation)
in 1 space and time variable:
· in weakly-nonlinear, dispersive, conservative wave equation for physical quantity (x, t); disper-
sion given by D(k, ) = 0, with solution = (k), or k = K() for modes ei[kx-t]
, and K
real and odd functions
· looking for slow, small deviations caused by nonlinearity of one monochromatic wave solution
(`mode'), described by complex amplitude A
A(x, t)ei[k0x-0t]
, k0 = K(0)
