    • 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) ...

    • Control of Volterra systems with scalar kernels 

      [OWP-2009-16] Haak, Bernhard Hermann; Jacob, Birgit (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-10)
      Volterra observations systems with scalar kernels are studied. New sufficient conditions for admissibility of observation operators are developed and some examples are discussed.

    • An introduction to heavy-tailed and sibexponential distributions 

      [OWP-2009-13] Foss, Sergey; Koršunov, Dmitrij; Zachary, Stan (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-07)
      This text studies heavy-tailed distributions in probability theory, and especially convolutions of such distributions. The mail goal is to provide a complete and comprehensive introduction to the theory of long-tailed ...

    • On Siegel modular forms of level p and their properties mod p 

      [OWP-2009-23] Böcherer, Siegfried; Nagaoka, Shoyu (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-16)
      Using theta series we construct Siegel modular forms of level p which behave well modulo p in all cusps. This construction allows us to show (under a mild condition) that all Siegel modular forms of level p and weight 2 ...

    • 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 ...

    • 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 ...

    • 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 ...
