    • Homological properties of piecewise hereditary algebras 

      [OWP-2009-11] Happel, Dieter; Zacharia, Dan (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-05)
      Let Λ be a finite dimensional algebra over an algebraically closed field k. We will investigate homological properties of piecewise hereditary algebras Λ. In particular we give lower and upper bounds of ...

    • A study on gradient blow up for viscosity solutions of fully nonlinear, uniformly elliptic equations 

      [OWP-2009-10] Kawohl, Bernhard; Kutev, Nickolai (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-04)
      We investigate sharp conditions for boundary and interior gradient estimates of continuous viscosity solutions to fully nonlinear, uniformly elliptic equations under Dirichlet boundary conditions. When these conditions are ...

    • Stein's method for dependent random variables occuring in statistical mechanics 

      [OWP-2009-09] Eichelsbacher, Peter; Löwe, Matthias (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-03)
      We obtain rates of convergence in limit theorems of partial sums Sn for certain sequences of dependent, identically distributed random variables, which arise naturally in statistical mechanics, in particular, in the ...

    • Classification of idempotent states on the compact quantum groups Uq(2), SUq(2) and SOq(3) 

      [OWP-2009-08] Franz, Uwe; Skalski, Adam; Tomatsu, Reiji (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-02)
      We give a simple characterisation of those idempotent states on compact quantum groups which arise as Haar states on quantum subgroups, show that all idempotent states on quantum groups Uq(2), SUq(2), and $SO_q(3) ...

    • Singer quadrangles 

      [OWP-2009-07] Winter, Stefaan de; Shult, Ernest E.; Thas, Koen (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-01)

    • Pointwise hyperbolicity implies uniform hyperbolicity 

      [OWP-2009-06] Hasselblatt, Boris; Pesin, Yakov B.; Schmeling, Jörg (Mathematisches Forschungsinstitut Oberwolfach, 2009-02-23)
      We provide a general mechanism for obtaining uniform information from pointwise data. A sample result is that if a diffeomorphism of a compact Riemannian manifold has pointwise expanding and contracting continuous invariant ...

    • On the non-analyticity locus of an arc-analytic function 

      [OWP-2009-03] Kurdyka, Krzysztof; Parusinski, Adam (Mathematisches Forschungsinstitut Oberwolfach, 2009-02-21)
      A function is called arc-analytic if it is real analytic on each real analytic arc. In real analytic geometry there are many examples of arc-analytic functions that are not real analytic. Arc analytic functions appear ...
