Neighbourhoods and isotopies of knots in contact 3-manifolds

  • Fan Ding
  • Hansjörg Geiges


We prove a neighbourhood theorem for arbitrary knots in contact 3-manifolds. As an application we show that two topologically isotopic Legendrian knots in a contact 3-manifold become Legendrian isotopic after suitable stabilisations.
