Convergence Analysis for the Recovery of the Friction Threshold in a Scalar Tresca Model
Erik Burman, Marvin Knöller, Lauri Oksanen +1
We consider a scalar valued elliptic partial differential equation on a sufficiently smooth domain , subject to a regularized Tresca friction-type boundary condition on a subse…

The temporal domain derivative in inverse acoustic obstacle scattering
Marvin Knöller, Jörg Nick
This work describes and analyzes the domain derivative for a time-dependent acoustic scattering problem. We study the nonlinear operator that maps a sound-soft scattering object to…

A Computational Method for the Inverse Robin Problem with Convergence Rate
Erik Burman, Marvin Knöller, Lauri Oksanen
The inverse Robin problem covers the determination of the Robin parameter in an elliptic partial differential equation posed on a domain . Given the solution of the Robin probl…
