Abstract/Media

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.
