Operators without eigenvalues in finite-dimensional vector spaces: Linearization and Spectral Equivalence

Branko Ćurgus, Aad Dijksma

In this paper $S$ is a closed symmetric linear relation in a Krein space $\mathfrak{H}$ with adjoint $S^{\ast }$, finite and equal defect numbers $d$, and a boundary mapping $\mathsf{b}:…
