Inverse problems with partial data for elliptic operators on unbounded Lipschitz domains
Jussi Behrndt, Jonathan Rohleder
For a second order formally symmetric elliptic differential expression we show that the knowledge of the Dirichlet-to-Neumann map or Robin-to-Dirichlet map for suitably many energi…

Two-dimensional Dirac operators with singular interactions supported on closed curves
Jussi Behrndt, Markus Holzmann, Thomas Ourmières-Bonafos +1
We study the two-dimensional Dirac operator with an arbitrary combination of electrostatic and Lorentz scalar -interactions of constant strengths supported on a smooth closed cu…
