Abstract

Let F1\mathcal{F}_1 and F2\mathcal{F}_2 be transverse two dimensional foliations with Gromov hyperbolic leaves in a closed 3-manifold MM whose fundamental group is not solvable, and let G\mathcal{G} be the one dimensional foliation obtained by intersection. We show that G\mathcal{G} is \emph{leafwise quasigeodesic} in F1\mathcal{F}_1 and F2\mathcal{F}_2 if and only if the foliation GL\mathcal{G}_L induced by G\mathcal{G} in the universal cover LL of any leaf of F1\mathcal{F}_1 or F2\mathcal{F}_2 has Hausdorff leaf space. We end up with a discussion on the hypothesis of Gromov hyperbolicity of the leaves.
