,Multiscale Expansions, Symmetries and the Nonlinear Schrödinger Hierarchy,ons, using a multitime expansion. In the case of pure radiation, we show that the asymptotic character of this expansion is guaranted by requiring that the modulation of the leading amplitude of the waves satisfy the nonlinear Schrodinger hierarchy of evolution equations with respect to the slow spaBIDE 发表于 2025-3-23 23:04:08
