    On rank one singular perturbations of selfadjoint operators (English)
    0 references
    The paper is devoted to the comparison of various approaches to the rank one singular perturbations of selfadjoint operators. In particular, the author establishes equivalence of their formulations in terms of resolvents, selfadjoint extensions, boundary conditions, additive sums, regularizations, approximations, and bilinear forms. As applications the Schrödinger operators with \(\delta\)-, \(\delta'\)-, and more general zero-range potentials are considered.
