Generalized Hopfian Property, Minimal Haken Manifold, and J. Simon’s Conjecture for 3-manifold Groups
We address a conjecture that π1-surjective maps between closed aspherical 3-manifolds having the same rank on π1 must be of non-zero degree. The conjecture is proved for Seifert manifolds, which is used in constructing the first known example of minimum Haken manifold. Another motivation is to study epimorphisms of 3-manifold groups via maps of non-zero degree between 3-manifolds. Section
متن کاملIsospectrality and 3-manifold Groups
In this note, we explain how a well-known construction of isospectral manifolds leads to an obstruction to a group being the fundamental group of a closed 3-dimensional manifold. The problem of determining, for a given group G, whether there is a closed 3-manifold M with π1(M) ∼= G is readily seen to be undecidable; let us write G ∈ G 3 if there is such a 3-manifold. A standard conjecture (rela...
متن کاملWhich 3-manifold Groups Are Kähler Groups?
The question in the title, first raised by Goldman and Donaldson, was partially answered by Reznikov. We give a complete answer, as follows: if G is both a (closed) 3-manifold group and a Kähler group, then G must be finite.
متن کامل3-manifold Groups and Nonpositive Curvature
We prove that the fundamental group of any compact Haken manifold of zero Euler characteristic, which is neither Nil nor Sol, is nonpositvely curved on the large scale.
متن کاملKähler groups, quasi-projective groups and 3-manifold groups
We prove two results relating 3-manifold groups to fundamental groups occurring in complex geometry. Let N be a compact, connected, orientable 3-manifold. If N has non-empty, toroidal boundary, and π1(N) is a Kähler group, then N is the product of a torus with an interval. On the other hand, if N has either empty or toroidal boundary, and π1(N) is a quasi-projective group, then all the prime co...
