不可约3-流形不能通过纽结上的0-外科手术获得

Irreducible 3-manifolds that cannot be obtained by 0-surgery on a knot

Matthew Hedden, Min Hoon Kim, Thomas E. Mark, Kyungbae Park

摘要:

我们给出了两个无限族的例子,封闭的,可定向的,不可约的3-流形$M$,使$b_1(M)=1$和$π_1(M)$的重量为1,但$M$是不是德恩手术的结果沿结在3球。这回答了一个问题的Aschenbrenner,弗里德尔和威尔顿,并提供了第一个例子的不可约流形与$b_1=1$是已知的不是外科手术的结在3球。一个族由塞弗特纤维3-流形组成,而另一个族的每个成员甚至不与任何塞弗特纤维3-流形同调协边。我们的例子中没有一个是同调共边的任何流形获得的德恩手术沿结的3球。

英文摘要:

We give two infinite families of examples of closed, orientable, irreducible 3-manifolds $M$ such that $b_1(M)=1$ and $π_1(M)$ has weight 1, but $M$ is not the result of Dehn surgery along a knot in the 3-sphere. This answers a question of Aschenbrenner, Friedl and Wilton, and provides the first examples of irreducible manifolds with $b_1=1$ that are known not to be surgery on a knot in the 3-sphere. One family consists of Seifert fibered 3-manifolds, while each member of the other family is not even homology cobordant to any Seifert fibered 3-manifold. None of our examples are homology cobordant to any manifold obtained by Dehn surgery along a knot in the 3-sphere.
