Inverse Boundary Problems for Systems in Two Dimensions

Pierre Albin, Colin Guillarmou, Leo Tzou +1

We prove identification of coefficients up to gauge by Cauchy data at the boundary for elliptic systems on oriented compact surfaces with boundary or domains of $C$ . In th…

Recovery of a source term or a speed with one measurement and applications

Plamen Stefanov, Gunther Uhlmann

We study the problem of recovery the source $a (t, x) F (x)$ in the wave equation in anisotropic medium with $a$ known so that $a (0, x) \neq = 0$ with a single measurement. We use Carleman…

Determining a first order perturbation of the biharmonic operator by partial boundary measurements

Katsiaryna Krupchyk, Matti Lassas, Gunther Uhlmann

We consider an operator $Δ^{2} + A (x) \cdot D + q (x)$ with the Navier boundary conditions on a bounded domain in $R^{n}$ , $n \geq 3$ . We show that a first order perturbation $A (x) \cdot D + q$ …

Inverse boundary value problems for the perturbed polyharmonic operator

Katsiaryna Krupchyk, Matti Lassas, Gunther Uhlmann

We show that a first order perturbation $A (x) \cdot D + q (x)$ of the polyharmonic operator $(- Δ)^{m}$ , $m \geq 2$ , can be determined uniquely from the set of the Cauchy data for the pertu…
