Abstract
We consider the quintic nonlinear Schrödinger equation ipartial tu=Delta uu4u in dimension N ≥ 3 This problem is energy critical in dimension N = 3 and energy super critical for N ≥ 4 We prove the existence of a radially symmetric blow up mechanism with L 2 concentration along the unit sphere of mathbbRN This singularity formation is moreover stable by smooth and radially symmetric perturbation of the initial data This result extends the result obtained for N = 2 in 29 and is the first result of description of a singularity formation in the energy supercritical class for NLS type problems Our main tool is the proof of the propagation of regularity outside the blow up sphere in the presence a socalled loglog type singularity
