Nonmanifold monodromy spaces of branched coverings between manifolds

چکیده
By a construction of Berstein and Edmonds every proper branched cover f between manifolds is factor covering orbit map from locally connected compact Hausdorff space called the monodromy to target manifold. For covers 2-manifolds known be We show that this does not generalize dimension 3 by constructing self-map 3-sphere for which contractible space.

Branched coverings, triangulations, and 3-manifolds
A canonical branched covering over each su‰ciently good simplicial complex is constructed. Its structure depends on the combinatorial type of the complex. In this way, each closed orientable 3-manifold arises as a branched covering over S from some triangulation of S. This result is related to a theorem of Hilden [11] and Montesinos [16]. The branched coverings introduced admit a rich theory in...
متن کاملOn branched coverings of some homogeneous spaces
We study nonsingular branched coverings of a homogeneous space X. There is a vector bundle associated with such a covering which was conjectured by O. Debarre to be ample when the Picard number of X is one. We prove this conjecture, which implies Barth-Lefschetz type theorems, for lagrangian grassmannians, and for quadrics up to dimension six. We propose a conjectural extension to homogeneous s...
متن کاملThree Manifolds as Geometric Branched Coverings of the Three Sphere
One method for obtaining every closed orientable 3-manifold is as a branched covering of S branched over a link. There are topological results along these lines that cannot be improved upon in two respects: (A), The minimum possible number of sheets in the covering is three; (B), There are individual knots and links (universal knots and links) that can serve as branch set for every 3-manifold, ...
متن کاملMonodromy Groups of Coverings of Curves
We consider nite separable coverings of curves f : X → Y over a eld of characteristic p ≥ 0. We are interested in describing the possible monodromy groups of this cover if the genus of X is xed. There has been much progress on this problem over the past decade in characteristic zero. Recently Frohardt and Magaard completed the nal step in resolving the Guralnick Thompson conjecture showing that...
متن کاملAlgorithmic aspects of branched coverings
This is the announcement, and the long summary, of a series of articles on the algorithmic study of Thurston maps. We describe branched coverings of the sphere in terms of group-theoretical objects called bisets, and develop a theory of decompositions of bisets. We introduce a canonical “Levy” decomposition of an arbitrary Thurston map into homeomorphisms, metrically-expanding maps and maps dou...
