Geometry and Topology Seminar: Tony Liimatainen, University of Helsinki, Finland, Geometric inverse problems and inverse problems for the minimal surface equation

February 14 | 11:00 am - 12:00 pm EST

We start by giving a short introduction to geometric inverse problems. Then we present our recent results regarding inverse problems for the minimal surface equation. Minimal surfaces are solutions to a quasilinear elliptic equation. We determine a minimal surface up to an isometry from the corresponding Dirichlet-to-Neumann map in dimension 2. Applications of the results include generalized boundary rigidity problem and AdS/CFT correspondence in physics. We develop nonlinear calculus for complex geometric optics solutions (CGOs) to handle numerous correction terms that appear in our analysis. The talk is based on a joint work with Catalin Carstea, Matti Lassas and Leo Tzou
