Foliation manifold

Webclosed three-manifold admits a one dimensional foliation; for example the three-sphere admits a foliation by round circles (Hopf) and by smooth lines [4]. Epstein, [3], showed that every foliation by circles is a Seifert bration, and this class of manifolds has been extensively studied. A manifold which bers over the circle WebThe fiber bundle yields a foliation by fibers . Its space of leaves is (diffeomeorphic) homeomorphic to , in particular is a Hausdorff manifold. [ 2.2 Suspensions A flat bundle has a foliation by fibres and it also has a foliation transverse to the fibers, whose leaves are where is the canonical projection.
