    • Tropical Algebraic Geometry 

      [OWS-35] Itenberg, Ilia; Mikhalkin, Grigory; Shustin, Eugenii (Birkhäuser Basel, 2007)
      Tropical geometry is algebraic geometry over the semifield of tropical numbers, i.e., the real numbers and negative infinity enhanced with the (max,+)-arithmetics. Geometrically, tropical varieties are much simpler than ...
    • A 3-local identification of the alternating group of degree 8, the McLaughlin simple group and their automorphism groups 

      [OWP-2007-02] Parker, Christopher; Rowley, Peter (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-20)
      In this article we give 3-local characterizations of the alternating and symmetric groups of degree 8 and use these characterizations to recognize the sporadic simple group discovered by McLaughlin from its 3-local subgroups.

      [OWP-2007-03] Niederkrüger, Klaus; Pasquotto, Federica (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-21)
      In this paper we present a method to obtain resolutions of symplectic orbifolds arising as quotients of pre-symplectic semi-free S1-actions. This includes, in particular, all orbifolds arising from symplectic reduction of ...

      [OWP-2007-04] Burban, Igor; Kreußler, Bernd (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-22)
      In this paper we introduce the notion of a gemetric associative r-matrix attached to a genus one fibration with a section and irreducible fibres. It allows us to study degenerations of solutions of the classical Yang-Baxter ...
