On -self-adjoint extensions of the Phillips symmetric operator
S. Kuzhel, O. Shapovalova, L. Vavrykovych
-self-adjoint extensions of the Phillips symmetric operator are studied. The concepts of stable and unstable -symmetry are introduced in the extension theory framework. T…

Singularly Perturbed Self-Adjoint Operators in Scales of Hilbert spaces
S. Albeverio, S. Kuzhel, L. Nizhnik
Finite rank perturbations of a semi-bounded self-adjoint operator A are studied in the scale of Hilbert spaces associated with A. A concept of quasi-boundary value space is used to…
