Abstract
Suppose that L is a null–homologous Legendrian knot in the contact 3– manifold (Y, ξ). We determine the connection between the sutured invariant EH(L) = EH(Y − ν(L), ξ|Y −ν(L)) of L and the Legendrian invariant b L(L) defined in [15]. In particular, we derive a vanishing theorem for b L(L) in the presence of Giroux torsion in the complement of the knot, and reprove several known proper ties of the Legendrian invariant from this perspective.
