边界为$\B^4$分支覆盖的紧Stein曲面

Compact Stein surfaces with boundary as branched covers of $\B^4$

Andrea Loi, Riccardo Piergallini

摘要:

证明了当分支集为正辫状曲面时,具有边界的Stein曲面与$\B^4$的简单分支覆盖的保向同构重合.因此,我们有一个光滑的定向3-流形是Stein可填充的当且仅当它有一个正的开卷分解。

英文摘要:

We prove that Stein surfaces with boundary coincide up to orientation preserving diffeomorphisms with simple branched coverings of $\B^4$ 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.
