  • The Method of Rigged Spaces in Singular Perturbation Theory of Self-Adjoint Operators
    Mykola Dudkin / Volodymyr Koshmanenko / Nataliia Koshmanenko
    This monograph presents the newly developed method of rigged Hilbert spaces as a modern approach in singular perturbation theory. A key notion of this approach is the Lax-Berezansky triple of Hilbert spaces embedded one into another, which specifies the well-known Gelfand topological triple. All kinds of singular interactions described by potentials supported on small sets (li...

  • Singular Quadratic Forms in Perturbation Theory
    Volodymyr Koshmanenko
    The notion of singular quadratic form appears in mathematical physics as a tool for the investigation of formal expressions corresponding to perturbations devoid of operator sense. Numerous physical models are based on the use of Hamiltonians containing perturba­ tion terms with singular properties. Typical examples of such expressions are Schrodin­ g...
