An inverse problem on determining second order symmetric tensor for perturbed biharmonic operator

Abstract This article offers a study of the Calderón type inverse problem determining up to second order coefficients higher elliptic operators. Here we show that it is possible determine an anisotropic perturbation given by symmetric matrix, along with first vector field and zero-th potential function inside bounded domain, measuring Dirichlet Neumann map perturbed biharmonic operator on boundary domain.
