### Abstract

We study the well-posedness of the Cauchy problem for Schrödinger maps from ℝ^{m} × ℝ into a compact Riemann surface N. The idea is to find an appropriate frame for u^{-1}TN so that the derivatives will satisfy a certain class of nonlinear Schrödinger equations; then the Strichartz estimates can be applied to obtain a priori estimates. We treat the problem with finite energy data for m = 1 and with small energy data for m = 2 under an assumption of radial or script S sign^{1} symmetry on N.
