Abstract:

For a bounded open set U in the plane and function q supported in U, the question of whether q is determined by the Dirichlet to Neumann map associated to the Schrodinger equation (Delta +q)u=0 was open for many years. A major breakthrough was achieved in 2008 by A. Bukhgeim who constructed special solutions to the Schrodinger equation which allowed the use of stationary phase. This talk will outline the construction and some subsequent developments.
