Abstract
We consider the cubic nonlinear Schrödinger equation (NLS) in one space dimension, either focusing or defocusing. We prove that the solutions satisfy a priori local in time Hs bounds in terms of the Hs size of the initial data for . This improves earlier results of Christ, Colliander and Tao [3], and of the authors (Koch and Tataru, 2007 [13]). The new ingredients are a localization in space and local energy decay, which we hope to be of independent interest.
