摘要：

We construct the "threshold manifold" near the soliton for the mass critical gKdV equation, completing results obtained in Martel et al. (Acta Math 212:59-140, 2014, J Math Eur Soc 2015). In a neighborhood of the soliton, this C (1) manifold of codimension one separates solutions blowing up in finite time and solutions in the "exit regime". On the manifold, solutions are global in time and converge locally to a soliton. In particular, the soliton behavior is strongly unstable by blowup.
