Aspects of a remarkable PDE

ABSTRACT We discuss some qualitative aspects of the Camassa-Holm equation: the blowup of certain solutions in finite time, the existence of global solutions, the soliton interaction of peaked solitary waves, the integrability of the equation (as an infinite-dimensional Hamiltonian system) and the connection with geodesic flow on the diffeomorphism group.
