Spectral estimates for resolvent differences of self-adjoint elliptic operators
Jussi Behrndt, Matthias Langer, Vladimir Lotoreichik
The notion of quasi boundary triples and their Weyl functions is an abstract concept to treat spectral and boundary value problems for elliptic partial differential equations. In t…
An inverse problem of Calderon type with partial data
Jussi Behrndt, Jonathan Rohleder
A generalized variant of the Calderón problem from electrical impedance tomography with partial data for anisotropic Lipschitz conductivities is considered in an arbitrary space di…
Eigenvalue estimates for singular left-definite Sturm-Liouville operators
Jussi Behrndt, Roland Moews, Carsten Trunk
The spectral properties of a singular left-definite Sturm-Liouville operator are investigated and described via the properties of the corresponding right-definite selfadjoint…
