MSRI - The Inverse Calderon Problem for Schrödinger Operator on Riemann Surfaces

Time:	11:00AM - 12:00PM
Location:	Simons Auditorium
Speakers:	Leo tzou, Leo tzou
Abstract:	We show that on a smooth compact Riemann surface with boundary (M0, g) the Dirichletto- Neumann map of the Schrödinger operator â g + V determines uniquely the potential V . This seemingly analytical problem turns out to have connections with ideas in symplectic geometry and differential topology. We will discuss how these geometrical features arise and the techniques we use to treat them. This is joint work with Colin Guillarmou of CNRS Nice.
