WebJun 12, 2011 · Reebless and taut foliations. Suppose we are given a closed oriented 3-manifold. It is well known that taut foliations are Reebless, and if a Reebless foliation isn't taut then the leaves which don't admit a closed transversal are tori. Furthermore, it is straightforward that in a taut foliation all the closed leaves are homologically non trivial. WebCHAPTER 4: FOLIATIONS AND FLOER THEORIES DANNYCALEGARI Abstract.

Here, we show that some other classes of essential laminations also give rise to actions on circles. In particular, we show this for tight essential laminations with solid torus guts. We also show that pseudo-Anosov flows induce actions on circles. … got error 13 from mount call

A taut foliation is a codimension 1 foliation of a closed manifold with the property that every leaf meets a transverse circle. By transverse circle, is meant a closed loop that is always transverse to the tangent field of the foliation. If … See more Taut foliations are closely related to the concept of Reebless foliation.

WebProperties of manifolds with taut foliation Question What are the topological/geometric consequences of having a taut foliation? Theorem (Palmeira, Rosenberg, Hae iger) If M is a closed, orientable 3-manifold that has a taut foliation with no sphere leaves then M is covered by R3, M is irreducible and has in nite fundamental group. Theorem ... WebOct 1, 2015 · Then the foliation is non-taut if and only if there is a basic vector field v on M such that div Q v ≥ 0 and div Q v > 0 at some point, where div Q is the transverse divergence operator associated to the metric g. Proof. We prove first that the above condition regarding the transverse divergence implies that the foliation is non-taut.

Thus F is taut if and only if g is unimodular and the H-orbit closures are minimal submanifolds for some H-invariant metric. WebWe define a norm on the homology of a foliated manifold, which refines and majorizes the usual Gromov norm on homology. This norm depends in an upper semi-continuous way on the underlying foliation, in the geometric topology. We show that this norm is non-trivial — i.e. it distinguishes certain taut foliations of a given hyperbolic 3-manifold.¶Using a …
