Abstract
Our framework here is low dimensional topology, and the main protagonists areLegendrian submanifolds, i.e. those which remains obediently tangent to thecontact hyperplane distribution. We will see the subtleties brought by Legendrianknots in comparison with classical smooth knots, and understand the naturalcobordism notion coming out, initiated by Arnol’d in the early 80’s: “What is a Legendrian surface between two Legendrian knots?” There will be infinitely many trivial knots, some bow ties, one swallow tail…and a lot of drawings.
