    • RESONANCES ON HEDGEHOG MANIFOLDS 

      Autor: Exner , Pavel; Lipovský , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      We discuss resonances for a nonrelativistic and spinless quantum particle confined to a two- or three-dimensional Riemannian manifold to which a finite number of semiinfinite leads is attached. Resolvent and scattering ...

    • Spectral Analysis of Schrödinger Operators with Unusual Semiclassical Behavior 

      Autor: Exner , Pavel; Barseghyan , Diana
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      In this paper we discuss several examples of Schrödinger operators describing a particle confined to a region with thin cusp-shaped ‘channels’, given either by a potential or by a Dirichlet boundary; we focus on cases when ...
