报告摘要:In this talk, we are concerned with the focusing mass-critical stochastic nonlinear Schrödinger equations, in the controlled rough path sense. In both dimensions one and two, the minimal mass blow-up solutions are constructed, particularly, in the absence of the pseudo-conformal symmetry and the conservation law of energy. This yields that the mass of ground state is exactly the threshold of global well-posedness and blow-up in the stochastic focusing mass-critical case. If time permits, the recent results on the existence and conditional uniqueness of multi-bubble blow-up solutions will be also presented. This talk is based on the work in joint with Yiming Su.
