Abstract
We consider a perturbed polyharmonic operator of order
defined on a bounded simply connected domain
with smooth connected boundary of the form:
where and
stands for the greatest integer function. In the biharmonic case, such operators arise in the study of certain elasticity and buckling problems. We study an inverse problem involving
and show that all the coefficients
, and
can be recovered from partial Dirichlet-to-Neumann (D-N) data on the boundary.
