The linearized Calder\'on problem for polyharmonic operators
Abstract
In this article we consider a linearized Calder\'on problem for polyharmonic operators of order 2m\ (m 2) in the spirit of Calder\'on's original work [Cal80]. We give a uniqueness result for determining coefficients of order ≤ 2m-1 up to gauge, based on inverting momentum ray transforms.
