Abstract:
Using the perturbation determinant introduced by B. Simon, we show the microscopic conservation laws for the Schwartz solutions of the derivative nonlinear Schrodinger equation (DNLS) with small mass, which can be used to show local smoothing estimate and global well-posedness of DNLS in the lower regularity space. It is a joint work with Xingdong Tang.
