Global Approximate Controllability of the Camassa-Holm Equation by a Finite Dimensional Force
Abstract
In this paper, we consider the Camassa-Holm equation posed on the periodic domain T. We show that Camassa-Holm equation is globally approximately controllable by three dimensional external force in Hs(T) for s > 32 . The proof is based on Agrachev-Sarychev approach in geometric control theory.
