On instability results in inverse problems
- Angkana Rüland (MPI MiS, Leipzig + University of Jyväskylä)
In general, inverse problems are notoriously ill-posed. As inverses of well-posed problems this, in particular, is reflected in their (in-)stability properties. In this talk I will discuss three robust, new mechanisms of proving (optimal) instability results for some classes of elliptic, parabolic and hyperbolic inverse problems. This is based on joint work with Herbert Koch and Mikko Salo.
