內(nèi)容介紹：In this talk, we will consider the location of the nucleation of instability of the Meissner solutions when the applied magnetic field is increased in the transition between the Meissner state and the vortex state. For superconductors with small penetration depth， our results show that the location is different in the case of the finite and infinite Ginzburg-Landau parameter. We also show that the solutions decay exponentially in the normal direction away from the boundary. This is a joint work with professor Xingbin Pan at CUHK-Shenzhen.
