Necessary conditions and sufficient conditions for global existence for two-components nonlinear Schrِdinger equations in the super critical case

In this paper, we consider two-components nonlinear Schrِdinger equations in the super critical case. We establish a necessary condition and a sufficient condition of global existence of the solution for two-components nonlinear Schrِdinger equations. These conditions are charge criterion of global existence in the super critical case, thereby extending the results in the critical case. Furthermore, we improve a blow-up condition.
