Open 3-manifolds and branched coverings: a quick exposition 3-variedades abiertas y cubiertas ramificadas
نویسنده
چکیده
Branched coverings relate closed, orientable 3-manifolds to links in S, and open, orientable 3-manifolds to strings in S r T , where T is a compact, totally disconnected tamely embedded subset of S. Here we give the foundations of this last relationship. We introduce Fox theory of branched coverings and state the main theorems. We give examples to illustrate the theorems.

Wild Branching Surfaces and Topological 4-manifolds
We prove that any closed connected oriented topological 4-manifold is a 4-fold topological simple branched cover of S4. As relevant intermediate steps, we extend the known branched covering representation for closed PL 4-manifolds to compact bounded and open PL 4-manifolds. Specifically, we show that any compact connected oriented PL 4-manifold with boundary is a simple branched cover of S4 min...
متن کاملEstimating Matveev's complexity via crystallization theory
In [M.R. Casali, Computing Matveev’s complexity of non-orientable 3-manifolds via crystallization theory, Topology Appl. 144(1–3) (2004) 201–209], a graph-theoretical approach toMatveev’s complexity computation is introduced, yielding the complete classification of closed non-orientable 3-manifolds up to complexity six. The present paper follows the same point-of view, making use of crystalliza...
متن کاملFinite groups acting on 3–manifolds and cyclic branched coverings of knots
We are interested in finite groups acting orientation-preservingly on 3–manifolds (arbitrary actions, ie not necessarily free actions). In particular we consider finite groups which contain an involution with nonempty connected fixed point set. This condition is satisfied by the isometry group of any hyperbolic cyclic branched covering of a strongly invertible knot as well as by the isometry gr...
متن کاملAbout Some Infinite Family of 2-bridge Knots and 3-manifolds
We construct an infinite family of 3-manifolds and show that these manifolds have cyclically presented fundamental groups and are cyclic branched coverings of the 3-sphere branched over the 2-bridge knots ( +1)2 or ( +1)1, that are the closure of the rational (2 −1)/( −1)–tangles or (2 −1)/ –tangles, respectively.
متن کاملOn periodic Takahashi manifolds
In this paper we show that periodic Takahashi 3-manifolds are cyclic coverings of the connected sum of two lens spaces (possibly cyclic coverings of S), branched over knots. When the base space is a 3-sphere, we prove that the associated branching set is a two-bridge knot of genus one, and we determine its type. Moreover, a geometric cyclic presentation for the fundamental groups of these manif...
