Bennequin, Daniel Links and Pfaffian equation. (Entrelacements et équations de Pfaff.) (French) Zbl 0573.58022 Astérisque 107/108, 87-161 (1983). The text gives a proof for the existence of nonisomorphic contact structures on the 3-dimensional Euclidean space. Principal themes: contact topology in dimension 3, linking properties of curves and plane fields, geometry of intersections of a surface with the Reeb foliation. Digressions: theory of braids, and analytic curves in the complex plane.For the entire collection see [Zbl 0516.00018].
