A globally convergent numerical method for a 3D coefficient inverse problem for a wave-like equation

Michael V. Klibanov, Jingzhi Li, Wenlong Zhang

A version of the convexification globally convergent numerical method is constructed for a coefficient inverse problem for a wave-like partial differential equation. The presence o…

Convexification for the inversion of a time dependent wave front in a heterogeneous medium

Michael V. Klibanov, Jingzhi Li, Wenlong Zhang

An inverse scattering problem for the 3D acoustic equation in time domain is considered. The unknown spatially distributed speed of sound is the subject of the solution of this pro…
