Legendrian curve A curve in a contact 3-manifold is called Legendrian if it is everywhere tangent to the contact planes.
Classification of overtwisted contact structures Martinet+Lutz+Eliashberg Overtwisted contact structures are classified: There is, up to isotopy, a unique overtwisted contact structure in every homotopy class of oriented plane fields.
Complement of the Hopf link in the 3-sphere fibers over the circle
