Determination of the density in a nonlinear elastic wave equation
Gunther Uhlmann, Jian Zhai
This is a continuation of our study [Uhlmann-Zhai, JMPA, 2021] on an inverse boundary value problem for a nonlinear elastic wave equation. We prove that all the linear and nonlinea…

Increasing stability estimates for the inverse potential scattering problems
Jian Zhai, Yue Zhao
This paper is mainly concerned with the inverse scattering problem of determining the unknown potential for the classical Schrödinger equation in two and three dimensions. We estab…
