Preconditioning Inverse Problems for Hyperbolic Equations with Applications to Photoacoustic Tomography

Alexander Beigl, Otmar Scherzer, Jarle Sogn +1

This paper is concerned with robust preconditioning of wave equations constrained linear inverse problems from boundary observation data. The main result of this paper is a concept…
