We show that on a smooth compact Riemann surface with boundary \((M_0,g)\) the Dirichlet-to-Neumann map of the Schrödinger operator \(\Delta_g+V\) 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.
