Abstract: In the first course, we discuss the definition of the Hamiltonians of the NLS hierarchy via direct scattering theory, and how to prove things about them. This involves working with recurrence relations and their generating functions.

In the second course, we discuss formal results on the structure of the Hamiltonians of the NLS hierarchy. As a result, we are able to prove the well-posedness of the NLS hierarchy in the setting of nonzero boundary data, and its approximation in the long-wave regime by the KdV hierarchy.
