N2 - Recent theoretical considerations link the nonlinear Schor dinger equation (NLSE) to localized envelope forms, known as breathers, which have been proposed as prototypes for extreme-amplitude excitations (freak waves, rogue waves) in various areas, including modulated-amplitude wavepackets in plasmas. The analytical methodology for the derivation of the NLSE is briefly reviewed, and its physical implications are discussed. A widespread “shortcut” methodology, relating it to small-amplitude theories for solitary waves, is shown to be inherently flawed, as regards its application in fluid plasma theory (notwithstanding the potential value of the method in other areas, e.g. in hydrodynamics).
