Attractor for the viscous two-component Camassa-Holm equation

摘要

This paper is concerned with the attractor for a viscous two-component generalization of the Camassa-Holm equation subject to an external force, where the viscosity term is given by a second order differential operator. The global existence of solution to the viscous two-component Camassa-Holm equation with the periodic boundary condition is studied. We obtain the compact and bounded absorbing set and the existence of the global attractor in ~(H2)× ~(H2) for the viscous two-component Camassa-Holm equation by uniform prior estimate and many inequalities.
