On Symmetries in the Theory of Finite Rank Singular Perturbations

Seppo Hassi, Sergii Kuzhel

For a nonnegative self-adjoint operator $A_{0}$ acting on a Hilbert space $H$ singular perturbations of the form $A_{0} + V, V = \sum_{1}^{n} b_{ij} < ψ_{j}, \cdot > ψ_{i}$ are studie…

On pseudo-Hermitian operators with generalized $C$ -symmetries

S. Kuzhel

The concept of $C$ -symmetries for pseudo-Hermitian Hamiltonians is studied in the Krein space framework. A generalization of $C$ -symmetries is suggested.
