A comparative study of structural similarity and regularization for joint inverse problems governed by PDEs

Benjamin Crestel, Georg Stadler, Omar Ghattas

Joint inversion refers to the simultaneous inference of multiple parameter fields from observations of systems governed by single or multiple forward models. In many cases these pa…

Sparse solutions in optimal control of PDEs with uncertain parameters: the linear case

Chen Li, Georg Stadler

We study sparse solutions of optimal control problems governed by PDEs with uncertain coefficients. We propose two formulations, one where the solution is a deterministic control o…
