Determination of Lower Order Perturbations of the Polyharmonic Operator from Partial Boundary Data

We consider a class of perturbed polyharmonic operators on a bounded simply connected domain of 3 and higher dimensional Euclidean space. In the biharmonic case, such operators arise in the study of certain elasticity and buckling problems. We study and inverse problem involving this operator and show that the perturbation coefficients can be recovered from partial boundary measurements.
