  • Gallone, Matteo; Michelangeli, Alessandro; Ottolini, Andrea (2017)
    The core results of the so-called KreIn-Visik-Birman theory of self-adjoint extensions of semi-bounded symmetric operators are reproduced, both in their original and in a more modern formulation, within a comprehensive ...
  • Michelangeli, Alessandro; Ottolini, Andrea (2016)
    For quantum systems of zero-range interaction we discuss the mathematical scheme within which modelling the two-body interaction by means of the physically relevant ultra-violet asymptotics known as the ``Ter-Martirosyan ...
  • Gallone, Matteo; Michelangeli, Alessandro (2017-06)
    We derive a classification of the self-adjoint extensions of the three-dimensional Dirac-Coulomb operator in the critical regime of the Coulomb coupling. Our approach is solely based upon the KreĬn-Višik- Birman extension ...
