   • 2015, Orsola Capovilla-Searle, Lisa Traynor, “Non-Orientable Lagrangian Cobordisms between Legendrian Knots”, in arXiv‎:

     We show that any Legendrian knot has a non-orientable Lagrangian endocobordism, and that the crosscap genus of such a non-orientable Lagrangian endocobordism must be a positive multiple of ${\displaystyle 4}$.
