Numerical study of the 2D Kaup-Broer-Kuperschmidt Boussinesq system

Théo Gaudry, Christian Klein, Jean-Claude Saut +1

In this work we consider the well posed version of the Kaup-Broer-Kuperschmidt system in two dimensions. We numerically construct soliton type solutions and show that they are unst…

Refined wave breaking for the generalized Fornberg-Whitham equation

Jean-Claude Saut, Yuexun Wang

This paper considers a class of non-local equations that are weakly dispersive perturbations of the inviscid Burgers equation, which includes the Fornberg-Whitham equation as a spe…

Refined wave breaking for the one-dimensional nonlinear shallow water equations

Pingchun Liu, Jean-Claude Saut, Shihan Sun +1

This paper aims to give a refined wave breaking description of the Cauchy problem to the one-dimensional nonlinear shallow water equations providing a sharp estimate of the lifespa…

Long time existence for a Boussinesq-like system with strong topography variation

Qi Lu, Jean-Claude Saut, Li Xu

We prove the long time existence of solutions of a Boussinesq system with strong topography variations.

Numerical study of the Amick-Schonbek system in 2D

C. Klein, J. -C. Saut

A numerical study of the 2D Amick-Schonbek Boussinesq system is presented. Numerical evidence is given for the transverse stability of the 1D solitary waves that are line solitary…

Long time existence for a class of weakly transverse Boussinesq systems

Qi Li, Jean-Claude Saut, Li Xu

We prove the existence on long time scales of the solutions to the Cauchy problem for a version of weakly transverse Boussinesq systems arising in the modeling of surface water wav…
