摘要
We show that the knowledge of the set of the Cauchy data on the boundary of a bounded open set in , , for the magnetic Schrodinger operator with L (a) magnetic and electric potentials, determines the magnetic field and electric potential inside the set uniquely. The proof is based on a Carleman estimate for the magnetic Schrodinger operator with a gain of two derivatives.
