Abstract

We show that any co-orientable foliation of dimension two on a closed orientable 33-manifold with continuous tangent plane field can be C0C^0-approximated by both positive and negative contact structures unless all the leaves are simply connected. As applications we deduce that the existence of a taut C0C^0-foliation implies the existence of universally tight contact structures in the same homotopy class of plane fields and that a closed 33-manifold that admits a taut C0C^0-foliation of codimension-1 is not an LL-space in the sense of Heegaard-Floer homology.
