Geometric tools were applied to study the dynamics of two- and three-peakon solutions of the Camassa-Holm equation. New proofs of the solutions' asymptotic behavior were provided, recovering well-known collision conditions. Additionally, the Gauss curvature (in the two-peakon case) and sectional curvature (in the three-peakon case) of corresponding manifolds were computed.
We apply geometric tools to study dynamics of two- and threepeakon solutions of the Camassa-Holm equation. New proofs of asymptotic behavior of the solutions are given. In particular we recover well-known collision conditions. Additionally the Gauss curvature (in the twopeakon case) and the sectional curvature (in the threepeakon case) of corresponding manifolds are computed.
