An alternative approach to the quasi-Periodic solutions of the Hunter-Saxton hierarchy
arXiv:1301.0690
Abstract
This paper is dedicated to provide the global solutions of algebro-geometric type for all the equations of a new commuting hierarchy containing the Hunter-Saxton (HS) equation. Our main tools include the zero curvature method to derive the HS hierarchy, the generalized Jacobian variety, the generalized Riemann theta function, the Weyl -fucntions , and the pole motion obtained by solving an inverse problem for the Sturm-Liouville equation . Based on these tools and the theory of nonautonomous differential systems, topological dynamics and ergodic theory, the algebro-geometric solutions are obtained for the entire HS hierarchy.
