Compact Stein Surfaces with Boundary as Branched Covers of B
We prove that Stein surfaces with boundary coincide up to orientation preserving diffeomorphisms with simple branched coverings of B4 whose branch set is a positive braided surface. As a consequence, we have that a smooth oriented 3-manifold is Stein fillable iff it has a positive open-book decomposition.
متن کاملCompact lsospectral Sets of Surfaces
In this paper we study sets of surfaces which are isospectral with respect to the Laplace-Beltrami operator. More specifically, for closed surfaces (compact, no boundary) we consider a fixed surface and the family of metrics on that surface having a given Laplace spectrum, whereas for surfaces with boundary we confine our study to the class of simply connected planar domains all having the same...
متن کاملConstructing Simplicial Branched Covers
Izmestiev and Joswig described how to obtain a simplicial covering space (the partial unfolding) of a given simplicial complex, thus obtaining a simplicial branched cover [Adv. Geom. 3(2):191-255, 2003]. We present a large class of branched covers which can be constructed via the partial unfolding. In particular, for d ≤ 4 every closed oriented PL d-manifold is the partial unfolding of some pol...
متن کاملRegular Covers of Open Relatively Compact Subanalytic Sets
Let U be an open relatively compact subanalytic subset of a real analytic manifold. We show that there exists a finite linear covering (in the sense of Guillermou and Schapira) of U by subanalytic open subsets of U homeomorphic to a unit ball. We also show that the algebra of open relatively compact subanalytic subsets of a real analytic manifold is generated by subsets subanalytically and bi-l...
متن کاملOn the existence of branched coverings between surfaces with prescribed branch data, I
For the existence of a branched covering Σ̃→ Σ between closed surfaces there are easy necessary conditions in terms of χ(Σ̃), χ(Σ), orientability, the total degree, and the local degrees at the branching points. A classical problem dating back to Hurwitz asks whether these conditions are also sufficient. Thanks to the work of many authors, the problem remains open only when Σ is the sphere, in wh...
