    • The Weil-Peterson Hessian of Length on Teichmuller Space 

      Wolf, Michael (2012)
      We present a brief but nearly self-contained proof of a formula for the Weil-Petersson Hessian of the geodesic length of a closed curve (either simple or not simple) on a hyperbolic surface. The formula is the sum of the ...

    • 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 ...
