  • Open Problems and Conjectures Related to the Theory of Mathematical Quasicrystals 

    Adiceam, Faustin; Damanik, David; Gähler, Franz; Grimm, Uwe; Haynes, Alan; Julien, Antoine; Navas, Andrés; Sadun, Lorenzo; Weiss, Barak (2016)
    This list of problems arose as a collaborative effort among the participants of the Arbeitsgemeinschaft on Mathematical Quasicrystals, which was held at the Mathematisches Forschungsinstitut Oberwolfach in October 2015. ...
  • Wigner-von Neumann type perturbations of periodic Schrödinger operators 

    Lukic, Milivoje; Ong, Darren C. (2015)
    Schrödinger operators on the half line. More precisely, the perturbations we consider satisfy a generalized bounded variation condition at infinity and an LP decay condition. We show that the absolutely continuous spectrum ...
  • Homology cobordism and Seifert fibered 3-manifolds 

    Cochran, Tim D.; Tanner, Daniel (2014)
    It is known that every closed oriented 3-manifold is homology cobordant to a hyperbolic 3-manifold. By contrast we show that many homology cobordism classes contain no Seifert fibered 3-manifold. This is accomplished by ...
