Necessary and Sufficient Conditions for S-hopfian Manifolds to Be Codimension-2 Fibrators
Fibrators help detect approximate fibrations. A closed, connected n-manifold N is called a codimension-2 fibrator if each map p : M → B defined on an (n + 2)-manifold M such that all fibre p−1(b), b ∈ B, are shape equivalent to N is an approximate fibration. The most natural objects N to study are s-Hopfian manifolds. In this note we give some necessary and sufficient conditions for s-Hopfian m...
متن کاملOn Certain 5-manifolds with Fundamental Group of Order 2
In this paper, an explicit classification result for certain 5-manifolds with fundamental group Z/2 is obtained. These manifolds include total spaces of circle bundles over simply-connected 4-manifolds.
متن کاملThe structure of 3-manifolds with 2-generated fundamental group
The main purpose of this article is to describe compact orientable irreducible 3-manifolds that have a non-trivial JSJ-decomposition and 2-generated fundamental group. The rank of a group is the minimal number of elements needed to generate it. A natural question is whether the Heegaard genus of such a manifold is equal to 2. When the JSJ-decomposition is empty, there are examples of closed 3ma...
متن کاملDiffeomorphisms of Manifolds with Finite Fundamental Group
We show that the group 3i{M) of pseudoisotopy classes of diffeomorphisms of a manifold of dimension > 5 and of finite fundamental group is commensurable to an arithmetic group. As a result n0{DiffM) is a group of finite type. Let M be an «-dimensional closed smooth manifold, where n > 5, and let DiffM be the group of diffeomorphisms of M. The space DiffM (it is a topological space with the C°°-...
متن کاملThe Fundamental Group of S1-manifolds
We address the problem of computing the fundamental group of a symplectic S-manifold for non-Hamiltonian actions on compact manifolds, and for Hamiltonian actions on non-compact manifolds with a proper moment map. We generalize known results for compact manifolds equipped with a Hamiltonian S-action. Several examples are presented to illustrate our main results.
