On extensions of linear functionals with applications to non-symmetrically singular perturbations

Abstract

The article is devoted to extensions of linear functionals, generated by scalar products, in a scale of Hilbert spaces. Such extensions are used to consider non-symmetrically singular rank one perturbations of ${\mathcal H}_{-2}$-class. For comparison, we give main definitions and descriptions of singular non-symmetric perturbations of ${\mathcal H}_{-1}$ and ${\mathcal H}_{-2}$-classes.

Key words: Scale of Hilbert spaces, functional, rigged Hilbert spaces, singular perturbations.
