扭曲Alexander多项式与纤维三维流形

Twisted Alexander polynomials and fibered 3-manifolds

Stefan Friedl, Stefano Vidussi

摘要:

在一系列论文中,作者证明了扭曲亚历山大多项式检测纤维3-流形,他们表明这意味着一个封闭的3-流形N是纤维的当且仅当S^1 x N是辛的。在这篇文章中,我们总结了证明的一些关键思想。我们还证明了如果$是一个具有自由S^1-作用的辛4-流形,那么它的轨道空间是纤维化的。

英文摘要:

In a series of papers the authors proved that twisted Alexander polynomials detect fibered 3-manifolds, and they showed that this implies that a closed 3-manifold N is fibered if and only if S^1 x N is symplectic. In this note we summarize some of the key ideas of the proofs. We also give new evidence to the conjecture that if $ is a symplectic 4-manifold with a free S^1-action, then the orbit space is fibered.
