摘要

We construct radially symmetric self-similar blow-up profiles for the mass supercritical nonlinear Schrodinger equation i partial derivative(t)u + Delta u + |u|(p-1)u = 0 on R-d, close to the mass critical case and for any space dimension d >= 1. These profiles bifurcate from the ground-state solitary wave. The argument relies on the classical matched asymptotics method suggested in Sulem and Sulem (The nonlinear Schrodinger equation. Selffocusing and wave collapse. Applied mathematical sciences, 139, Springer, New York, 1999) which needs to be applied in a degenerate case due to the presence of exponentially small terms in the bifurcation equation related to the log-log blow-up law observed in the mass critical case.
