缝合弗洛尔同调上的同调作用

Homological actions on sutured Floer homology

Yi Ni

摘要:

定义了同调群$H_1(M,\partial M)$在缝合的弗洛尔同调$SFH(M,γ)$上的作用.事实证明,接触不变量$EH(M,γ,ξ)$通常通过此操作被发送到零。这一事实使我们能够改进早先由Ghiggini和作者证明的结果。作为推论,我们在$#^n(S^1\times S^2)$中对具有简单结弗洛尔同调群的结进行了分类:它们本质上是波罗米安结。

英文摘要:

We define the action of the homology group $H_1(M,\partial M)$ on the sutured Floer homology $SFH(M,γ)$. It turns out that the contact invariant $EH(M,γ,ξ)$ is usually sent to zero by this action. This fact allows us to refine an earlier result proved by Ghiggini and the author. As a corollary, we classify knots in $#^n(S^1\times S^2)$ which have simple knot Floer homology groups: They are essentially the Borromean knots.
