Outline of Final Research Achievements

The research results are as follows. (1) We proved the well-posedness and ill-posedness of the Cauchy problem for the one dimensional Chern-Simons-Dirac system. We completely determined the range, which is not convex, of Sobolev regularity to be well-posed. (2) We proved the global well-posedness and scattering for the fourth order nonlinear Schrodinger equation. (3) We obtain the well-posedness and ill-posedness results of the Cauchy problem for the generalized Thirring model.
