In this paper we shall use realization theory, a favourite technique of Rien Kaashoek, to prove new results about a class of holomorphic functions on an annulus R δ = def { z ∈ C : δ

We thoroughly analyse the double-layer potential's role in approaches to spectral sets in the spirit of Delyon-Delyon, Crouzeix and Crouzeix-Palencia. While the potential is well-studied, we aim to clarify on several of its aspects in light...

In this note the two dimensional Dirac operator A η with an electrostatic δ -shell interaction of strength η ∈ R supported on a straight line is studied. We observe a spectral transition in the sense that for the crit...

We couple the mixed variational problem for the generalized Hodge-Helmholtz or Hodge-Laplace equation posed on a bounded 3D Lipschitz domain with the first-kind boundary integral equations arising from the latter when constant coefficients ...
