• On Generalizations of Kac-Moody Groups 

      [OWP-2010-06] Blok, Rieuwert J.; Hoffman, Corneliu (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-10)
      In [7] we define a Curtis-Tits group as a certain generalization of a Kac-Moody group. We distinguish between orientable and non-orientable Curtis-Tits groups and identify all orientable Curtis-Tits groups as Kac-Moody ...
    • 1318a - Progress in Surface Theory 

      [OWR-2013-21] (2013) - (28 Apr - 04 May 2013)
      Over the last 30 years global surface theory has become pivotal in the understanding of low dimensional global phenomena. At the same time surface geometry became a platform on which seemingly different areas of mathematics ...
    • Supertropical linear algebra 

      [OWP-2010-14] Izhakian, Zur; Knebusch, Manfred; Rowen, Louis (Mathematisches Forschungsinstitut Oberwolfach, 2010)
      The objective of this paper is to lay out the algebraic theory of supertropical vector spaces and linear algebra, utilizing the key antisymmetric relation of "ghost surpasses." Special attention is paid to the various ...
    • 1607a - Topological Recursion and TQFTs 

      [OWR-2016-9] (2016) - (14 Feb - 20 Feb 2016)
      The topological recursion is an ubiquitous structure in enumerative geometry of surfaces and topological quantum field theories. Since its invention in the context of matrix models, it has been found or conjectured to ...
