摘要:In this talk, we consider the inverse boundary value problem of the Schrodinger operator in a bounded domain with unknown embedded obstacles. We will propose a new and simple proof to uniquely determine the potential function and all of its derivatives at the boundary from the local Dirichlet-to-Neumann map, where the knowledge of the fundamental solution is only used. Our proof mainly depends on the rigorous singularity analysis on certain singular solutions and the volume potentials with the weak singular kernel, which is easily extended to many other cases.
