Résumé : 

Using the grid diagram formulation of knot Floer homology, Ozsvath, Szabo and Thurston defined an invariant of transverse knots in the tight contact 3-sphere. Shortly afterwards, Lisca, Ozsvath, Stipsicz and Szabo defined an invariant of transverse knots in arbitrary contact 3-manifolds using open book decompositions. It has been conjectured that these invariants agree where they are both defined. In this talk, I prove this fact by defining yet another invariant of transverse knots, showing that this third invariant agrees with the two mentioned above.

This is a joint work with John A. Baldwin and David Shea Vela-Vick.
