报告摘要:

We present two different approaches that showing the stable blow-up solutions in the L^2-critical NLS equation (the log-log blow-up dynamics up to the dimension 12). One approach is the direct numerical simulation via the "Dynamic rescaling method", and then combined with the asymptotic analysis of the rescaled equation. The other approach is to prove the Spectral property with the numerical assistance. Then, use such Spectral property in the analysis to complete the proof. Then, we would like to show the similar numerical results (from the Dynamic rescaling method) that we obtained for the generalized Hartree equation (the NLS equation with non-local potential).
