The "good'' Boussinesq equation: long-time asymptotics

Analysis of PDEs 2023-08-30 v1 Exactly Solvable and Integrable Systems

Abstract

We consider the initial-value problem for the ``good'' Boussinesq equation on the line. Using inverse scattering techniques, the solution can be expressed in terms of the solution of a 3×33 \times 3-matrix Riemann-Hilbert problem. We establish formulas for the long-time asymptotics of the solution by performing a Deift-Zhou steepest descent analysis of a regularized version of this Riemann-Hilbert problem.
