Existence and uniqueness of the solution to the modified Schrödinger mapAuthors: Jun Kato
Author institution: Kyoto University
Summary: We prove the local existence of the solution to a certain system of nonlinear Schrödinger equations arising from Schrödinger maps for the initial data in $H^{s}(\mathbf{R}^{2})$ with $s>1/2$. The uniqueness of the solution is also proved when the data belong to $H^{1}(\mathbf{R}^{2})$.
