Abstract
We investigate the bi-Hamiltonian formulation for the nonlinear derivative Schroedinger-equation. The underlying symplectic and implectic operators can be inverted explicitly yielding a Laxhierarchy of both local and nonlocal symmetry transformations and conservation laws. An infinite sequence of mastersymmetries for this hierarchy is constructed.Keywords
