Improved almost Morawetz estimates for the cubic nonlinear Schrodinger equation

Published 2009-09-04, updated 2009-09-06Version 2

We prove global well-posedness for the cubic, defocusing, nonlinear Schr{\"o}dinger equation on $\mathbf{R}^{2}$ with data $u_{0} \in H^{s}(\mathbf{R}^{2})$, $s > 1/4$. We accomplish this by improving the almost Morawetz estimates in [9].
