Explicit multipeakon solutions of Novikov's cubically nonlinear integrable Camassa-Holm type equation

Andrew N. W. Hone, Hans Lundmark, Jacek Szmigielski

Recently Vladimir Novikov found a new integrable analogue of the Camassa-Holm equation, admitting peaked soliton (peakon) solutions, which has nonlinear terms that are cubic, rathe…
