An inverse conductivity problem in multifrequency electric impedance tomography
Jin Cheng, Mourad Choulli, Shuai Lu
We deal with the problem of determining the shape of an inclusion embedded in a homogenous background medium. The multifre-quency electrical impedance tomography is used to image t…

Linearized inverse Schrödinger potential problem at a large wavenumber
Victor Isakov, Shuai Lu, Boxi Xu
We investigate recovery of the (Schrödinger) potential function from many boundary measurements at a large wavenumber. By considering such a linearized form, we obtain a Hölder typ…
