Abstract
The behaviour of solutions of nonlinear Schrodinger (NLS) equation of derivative type was discussed in the semiclassical limit. The genuine nonlinearity and strict hyperbolicity was proved for the dispersion limit of the derivative nonlinear Schrodinger equation (DNLS) while Riemann invariants remained distinct. The hydrodynamical structure and the local conservation laws of the DNLS of type II were established.
