Unphysical energy sheets and resonances in the Friedrichs-Faddeev model

Alexander K. Motovilov

We consider the Friedrichs-Faddeev model in the case where the kernel of the potential operator is holomorphic in both arguments on a certain domain of $C$ . For this model…

Preserving of the unconditional basis property under non-self-adjoint perturbations of self-adjoint operators

Alexander K. Motovilov, Andrei A. Shkalikov

Let $T$ be a self-adjoint operator in a Hilbert space $H$ with domain $D (T)$ . Assume that the spectrum of $T$ is confined in the union of disjoint intervals $Δ_k =[α_{2k-1…
