Abstract:

We show that a first order perturbation $A(x)\cdot D+q(x)$ of the polyharmonic operator $(-\Delta )^m$, $m\ge 2$, can be determined uniquely from the set of the Cauchy data for the perturbed polyharmonic operator on a bounded domain in $\mathbb {R}^n$, $n\ge 3$. Notice that the corresponding result does not hold in general when $m=1$.
