Outline of Final Research Achievements |
In this research, we have studied the asymptotic behavior of blow-up solution and solitons of nonlinear dispersive equations. In particular, with Kishimoto, I have constructed a blow-up solution for Zakharov equation on a torus and with Suzuki, I have constructed a solution for stationary nonlinear Schrodinger equation in a thin domain which concentrated on a short line. Moreover, with Cuccagna, I have studied the asymptotic stability of fast speed soliton. By the analysis of the soliton we have developed a new method wich is based on the Hamiltonian structure of the equation. This method is expected to give a new perspective for the analysis of general nonlinear dispersive equations.
