Summary
We consider the scattering transform for the first-order system in the plane,
$$\left( {\begin{array}{*{20}c}
{\partial _{\bar x} } & 0 \\
0 & {\partial _x } \\
\end{array} } \right)\psi - \left( {\begin{array}{*{20}c}
0 & {q^1 } \\
{q^2 } & 0 \\
\end{array} } \right)\psi = 0.$$
We show that the scattering map is Lipschitz continuous on a neighborhood of zero in L 2.
