Finite Covers of 3-manifolds Containing Essential Tori
It is shown in this paper that if a Haken 3-manifold contains an incompressible torus that is not boundary-parallel then either it has a finite cover that is a torus-bundle over the circle or it has finite covers with arbitrarily large first Betti number. In [He 4], Hempel conjectures that every Haken 3-manifold has a finite cover whose fundamental group has a nontrivial representation to the i...
متن کاملRelative Euler Number and Finite Covers of Graph Manifolds
In this paper we show that every non-trivial graph manifold M has a finite cover that contains a foliation which is very close to a fibration over the circle — the foliation restricted to each vertex manifold of M is a fibration over the circle. On the other hand, we show that this foliation can not always be made to be a fibration over the circle, by exhibiting a large class of graph manifolds...
متن کاملFinite covers of random 3 - manifolds
A 3-manifold is Haken if it contains a topologically essential surface. The Virtual Haken Conjecture posits that every irreducible 3-manifold with infinite fundamental group has a finite cover which is Haken. In this paper, we study random 3-manifolds and their finite covers in an attempt to shed light on this difficult question. In particular, we consider random Heegaard splittings by gluing t...

متن کاملEssential Closed Surfaces in Bounded 3-manifolds
A question dating back to Waldhausen [10] and discussed in various contexts by Thurston (see [9]) is the problem of the extent to which irreducible 3-manifolds with infinite fundamental group must contain surface groups. To state our results precisely, it is convenient to make the definition that a map i : S # M of a closed, orientable connected surface S is essential if it is injective at the ...
