摘要:

我们研究4维流形中局部平坦、紧致、定向面,其外部具有无限循环基本群。我们给出两个具有相同亏格g的此类面通过环境同胚相关联的代数拓扑条件,并进一步给出证明它们通过环境同伦的条件。在此过程中,我们证明了某些具有无限循环基本群、同胚边界和等价等变交割形式的拓扑4维流形是同胚的。

英文摘要:

We study locally flat, compact, oriented surfaces in $4$-manifolds whose exteriors have infinite cyclic fundamental group. We give algebraic topological criteria for two such surfaces, with the same genus $g$, to be related by an ambient homeomorphism, and further criteria that imply they are ambiently isotopic. Along the way, we prove that certain pairs of topological $4$-manifolds with infinite cyclic fundamental group, homeomorphic boundaries, and equivalent equivariant intersection forms, are homeomorphic.
