    • Braid equivalences and the L-moves 

      [OWP-2011-20] Lambropoulou, Sofia (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-19)
      In this survey paper we present the L-moves between braids and how they can adapt and serve for establishing and proving braid equivalence theorems for various diagrammatic settings, such as for classical knots, for knots ...

    • Legendrian Knots in Lens Spaces 

      [OWP-2011-01] Onaran, Sinem (Mathematisches Forschungsinstitut Oberwolfach, 2011)
      In this note, we first classify all topological torus knots lying on the Heegaard torus in Lens spaces, and then we classify Legendrian representatives of torus knots. We show that all Legendrian torus knots in universally ...

    • Products of pairs of Dehn twists and maximal real Lefschetz fibrations 

      [OWP-2011-32] Degtyarev, Alex; Salepci, Nermin (Mathematisches Forschungsinstitut Oberwolfach, 2011)
      We address the problem of existence and uniqueness of a factorization of a given element of the modular group into a product of two Dehn twists. As a geometric application, we conclude that any maximal real elliptic ...
