"The Camassa-Holm equation and geometry of peakons"
Abstract
Multipeakons are special solutions to the Camassa-Holm equation. They can be described in terms of a geodesic flow on a Riemannian manifold. Singular points of the underlying metric correspond to collisions of the multipeakons. I shall investigate the metric near its singular points in order to analyse the dissipative prolongations of the multipeakons after a collision time.
