Dispersive decay of small data solutions for the KdV equation

Analysis of PDEs 2022-01-04 v2

Abstract

We consider the Korteweg-de Vries (KdV) equation, and prove that small localized data yields solutions which have dispersive decay on a quartic time-scale. This result is optimal, in view of the emergence of solitons at quartic time, as predicted by inverse scattering theory.
