We present a new method for obtaining sharp asymptotics of solutions of the defocussing nonlinear Schr\"odinger (NLS) equation, based on dbar methods and under essentially minimal regularity assumptions on initial data.

  1. Large-time asymptotics for the defocusing Manakov system on a nonzero background

    nlin.SI 2025-12 conditional novelty 7.0 of 10

    The defocusing Manakov system on a nonzero background has long-time soliton-region asymptotics given by a modulated N-soliton plus an explicit t^{-1/2} radiation correction.

  2. Soliton resolution for the coupled complex short pulse equation

    nlin.SI 2025-05 conditional novelty 6.0 of 10

    For the coupled complex short pulse equation, long-time solutions split into self-symmetric solitons or composite breathers plus t^{-1/2} radiation, with O(t^{-1} ln t) errors, while the opposite sector decays as O(t^{-1}).

  3. Asymptotic stability of solutions to the good Boussinesq equation in dispersive wave region

    math-ph 2026-07 conditional novelty 5.5 of 10

    Long-time asymptotics of the good Boussinesq equation are obtained via Dbar-steepest descent for reflection coefficients in H^{3,4}, yielding an optimal O(t^{-3/4}) error and asymptotic stability in the dispersive region.
