  • Singularly perturbed self-adjoint operators in scales of Hilbert spaces 
    Albeverio, S.; Kuzhel, S.; Nizhnik, L. (Український математичний журнал, 2007)
    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 describe self-adjoint operator realizations ...
