A Justification of the Modulation Approximation to the 3D Full Water Wave Problem

, 2014
We consider small amplitude wave packet-like solutions to the 3D inviscid incompressible irrotational infinite depth water wave problem neglecting surface tension. Formal multiscale calculations suggest that the modulation of such a solution is described
