• Locally conformally Kähler manifolds admitting a holomorphic conformal flow 

      [OWP-2010-13] Ornea, Liviu; Verbitsky, Misha (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-15)
      A manifold M is locally conformally Kähler (LCK) if it admits a Kähler covering ˜M with monodromy acting by holomorphic homotheties. Let M be an LCK manifold admitting a holomorphic conformal flow of ...
    • On Selfinjective Artin Algebras Having Generalized Standard Quasitubes 

      [OWP-2010-18] Karpicz, Maciej; Skowroński, Andrzej; Yamagata, Kunio (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-18)
      We give a complete description of the Morita equivalence classes of all connected selfinjective artin algebras for which the Auslander-Reiten quiver admits a family of quasitubes having common composition factors, closed ...
    • Plethysms, replicated Schur functions and series, with applications to vertex operators 

      [OWP-2010-12] Fauser, Bertfried; Jarvis, Peter D.; King, Ronald C. (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-14)
      Specializations of Schur functions are exploited to define and evaluate the Schur functions sλ[αX] and plethysms sλ[αsν(X))] for any α-integer, real or complex. Plethysms are then ...
    • Semi-Invertible Extensions of C*-Algebras 

      [OWP-2010-17] Manujlov, Vladimir M.; Thomsen, Klaus (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-17)
      We prolonge the list of C-algebras for which all extensions by any stable separable C-algebra are semi-invertible. In particular, we handle certain amalgamations, both of C-algebras and of groups. Concerning ...
    • Shape Theory and Extensions of C*-Algebras 

      [OWP-2010-16] Manujlov, Vladimir M.; Thomsen, Klaus (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-16)
      Let A, A' be separable C-algebras, B a stable σ-unital C-algebra. Our main result is the construction of the pairing [[A,A]]×Ext1/2(A,B)Ext1/2(A,B), where [[A,A]] denotes the ...
    • Stochastic mean payoff game: smoothed analysis and approximation schemes 

      [OWP-2010-22] Boros, Endre; Elbassioni, Khaled; Fouz, Mahmoud; Gurvich, Vladimir; Manthey, Bodo (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-20)
      We consider two-person zero-sum stochastic mean payoff games with perfect information modeled by a digraph with black, white, and random vertices. These BWR-games games are polynomially equivalent with the classical Gillette ...
    • Unconditional Convergence of Spectral Decompositions of 1D Dirac Operators with Regular Boundary Conditions
