On a boundary pair of a dissipative operator
Rytis Jursenas
The aim of this brief note is to demonstrate that the boundary pair of a dissipative operator is determined by the unitary boundary pair of its symmetric part.

On the similarity of boundary triples for dual pairs
Rytis Jursenas
The Weyl family of a dual pair of operators in a Krein space determines a minimal boundary triple uniquely up to similarity; if , a necessary and sufficient c…

Locus of non-real eigenvalues of a class of linear relations in a Krein space
Rytis Jursenas
It is a classical result that, if a maximal symmetric operator in a Krein space has the property $\mathcal{H}^-\subseteq\mathca…
