摘要

We establish that the initial value problem for the quadratic non-linear Schr\"odinger equation $iu_t - \Delta u = u^2$ where $u: \R^2 \times \R \to \C$ , is locally well-posed in $H^s(\R^2)$ when $s > -1$ . The critical exponent for this problem is $s_c=-1$ and previous work in \cite{c1} established local well-posedness for $s > -3/4$ .
