The 3D critical Zakharov--Kuznetsov equation: blow-up and soliton dynamics

Christian Klein, Svetlana Roudenko, Nikola Stoilov

We study the full three-dimensional dynamics of the -critical Zakharov-Kuznetsov equation with the fractional nonlinearity , equivalently for real-valued…

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…

Nonlinear Schrödinger equation on a unit ball in one and two dimensions

Christian Klein, Svetlana Roudenko, Nikola Stoilov

We consider the nonlinear Schrödinger equation on a unit ball in one and two dimensions with Dirichlet boundary conditions, which have stabilizing effect on solutions behavior. In…

Numerical study of Davey-Stewartson I systems

J. Frauendiener, C. Klein, U. Muhammad +1

An efficient high precision hybrid numerical approach for integrable Davey-Stewartson (DS) I equations for trivial boundary conditions at infinity is presented for Schwartz class i…
