   报告摘要：

   We consider the travelling wave solutions of the Gross-Pitaevskii equation in the plane. In the zero speed or subsonic region, we construct solutions using the theory of integrable systems, including KdV and KP equations. When the speed is close to zero, the solutions are modeled on the vortex solutions of the Ginzburg-Landau equation; in the subsonic limit case, the solutions are modeled on the lump solutions of the KP-I equation. This is joint work with Juncheng Wei at UBC
