报告内容: In this talk, we survey recent results on the Liouville correspondences of integrable hierarchies. The Liouville transformation between the isospectral problems of the two integrable hierarchies is shown to establish the Liouville correspondence between their flows and Hamiltonian functionals. As prototypical examples, the motivation and framework for constructing Liouville correspondences of the modified Camassa-Holm hierarchy, the Novikov hierarchy, the Degasperis-Procesi hierarchy, the two-component Camassa-Holm hierarchy and the two-component Novikov (Geng-Xue) hierarchy is discussed. |
