A Linearized Boundary Control Method for the Acoustic Inverse Boundary Value Problem

Inverse Problems, 2021
We develop a linearized boundary control method for the inverse boundary value problem of determining a potential in the acoustic wave equation from the Neumann-to-Dirichlet map. When the linearization is at the zero potential, we derive a reconstruction

Optimality of Increasing Stability for an Inverse Boundary Value Problem [PDF]

SIAM Journal on Mathematical Analysis, 2021
In this work we study the optimality of increasing stability of the inverse boundary value problem (IBVP) for Schrödinger equation. The rigorous justification of increasing stability for the IBVP for Schrödinger equation were established by Isakov \cite{Isa11} and by Isakov, Nagayasu, Uhlmann, Wang of the paper \cite{INUW14}.
