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…

Spectral inclusion and spectral exactness for singular non-selfadjoint Sturm-Liouville problems
B. M. Brown, M. Marletta
We consider the effect of regularization by interval truncation on the spectrum of a singular non-selfadjoint Sturm-Liouville operator. We present results on spectral inclusion and…

On a conjecture of Bennewitz, and the behaviour of the Titchmarsh-Weyl matrix near a pole
B. M. Brown, M. Marletta
For any real limit- th-order selfadjoint linear differential expression on , Titchmarsh- Weyl matrices can be defined. Two matrices of particu lar interes…
