The spectral form of the functional model for maximally dissipative operators: A Lagrange identity approach
B. Malcolm Brown, Marco Marletta, Sergey Naboko +1
The spectral and scattering properties of non-selfadjoint problems pose a mathematical challenge. Apart from exceptional cases, the well-developed methods used to examine the spect…
Spectral analysis and domain truncation methods for Maxwell's equations
Sabine Boegli, Francesco Ferraresso, Marco Marletta +1
We analyse how the spectrum of the anisotropic Maxwell system with bounded conductivity on a Lipschitz domain is approximated by domain truncation. First we prove a new non-convex…
An abstract inverse problem for boundary triples with an application to the Friedrichs Model
B. M. Brown, M. Marletta, S. N. Naboko +1
We discuss the detectable subspaces of an operator. We analyse the relation between the M-function (the abstract Dirichlet to Neumann map) and the resolvent bordered by projections…
On a class of non-self-adjoint periodic boundary value problems with discrete real spectrum
Lyonell Boulton, Michael Levitin, Marco Marletta
In [arXiv:0801.0172] we examined a family of periodic Sturm-Liouville problems with boundary and interior singularities which are highly non-self-adjoint but have only real eigenva…
