The anisotropic Calderón problem at large fixed frequency on manifolds with invertible ray transform
Shiqi Ma, Suman Kumar Sahoo, Mikko Salo
We consider the inverse problem of recovering a potential from the Dirichlet to Neumann map at a large fixed frequency on certain Riemannian manifolds. We extend the earlier result…

An inverse problem for semilinear equations involving the fractional Laplacian
Pu-Zhao Kow, Shiqi Ma, Suman Kumar Sahoo
Our work concerns the study of inverse problems of heat and wave equations involving the fractional Laplacian operator with zeroth order nonlinear perturbations. We recover nonline…
