Ill-posedness of the third order NLS equation with Raman scattering term
Pages: 1447 – 1484
We consider the ill-posedness and well-posedness of the Cauchy problem for the third order NLS equation with Raman scattering term on the one dimensional torus. It is regarded as a mathematical model for the photonic crystal fiber oscillator. Regarding the illposedness, we show the nonexistence of solutions in the Sobolev space and the norm inflation of the data-solution map at the origin under slightly different conditions, respectively. We also prove the local unique existence of solutions in the analytic function space.
