wave breaking. By introducing a new set of independent and dependent variables, the …

[HTML][HTML] A view of the peakon world through the lens of approximation theory

H Lundmark, J Szmigielski - Physica D: Nonlinear Phenomena, 2022 - Elsevier
Peakons (peaked solitons) are particular solutions admitted by certain nonlinear PDEs, most
famously the Camassa–Holm shallow water wave equation. These solutions take the form of …

Bäcklund transformations for the Camassa–Holm equation

AG Rasin, J Schiff - Journal of Nonlinear Science, 2017 - Springer
The Bäcklund transformation (BT) for the Camassa–Holm (CH) equation is presented and
discussed. Unlike the vast majority of BTs studied in the past, for CH the transformation acts …

Global conservative multipeakon solutions of the Camassa–Holm equation

H Holden, X Raynaud - Journal of Hyperbolic Differential Equations, 2007 - World Scientific
We show how to construct globally defined multipeakon solutions of the Camassa–Holm
