Approximating C0-foliations by contact structures
We show that any co-orientable foliation of dimension two on a closed orientable 3-manifold with continuous tangent plane field can be C 0 -approximated by both positive and negative contact structures unless all leaves of the foliation are simply connected. As applications we deduce that the existe...
