We show that every closed, toroidal, irreducible, orientable 3-manifold carries infinitely many universally tight contact structures.¶¶Résumé. On démontre que toute variété orientable, irréductible, close et toroïdale de dimension 3 porte une infinité de structures de contact universellement tendues.

Une infinité de structures de contact tendues sur les variétés toroïdales
