Cloaking for a quasi-linear elliptic partial differential equation

Tuhin Ghosh, Karthik Iyer

In this article we consider cloaking for a quasi-linear elliptic partial differential equation of divergence type defined on a bounded domain in $R^{N}$ for $N = 2, 3$ . We show…

Determining rough first order perturbations of the polyharmonic operator

Yernat M. Assylbekov, Karthik Iyer

We show that the knowledge of Dirichlet to Neumann map for rough $A$ and $q$ in $(- Δ)^{m} + A \cdot D + q$ for $m \geq 2$ for a bounded domain in $R^{n}$ , $n \geq 3$ determines $…
