纽结弗洛尔同调与不动点

Knot Floer homology and fixed points

Yi Ni

摘要:

如果$K$是一个纤维纽结在一个封闭的,有向的$3$ -流形$Y$与纤维$F$,和$\widehat{HFK}(Y,K,[F], g(F)-1;\mathbb Z/2\mathbb Z)$有秩$r$,那么$K$的单值是自由同位素到一个单同态与最多$r-1$不动点。这概括了鲍德温-胡-西韦克和倪早期的工作。我们还澄清了一个误导性的公式在棉花粘土的计算辛弗洛尔同调的映射类的表面。

英文摘要:

If $K$ is a fibered knot in a closed, oriented $3$--manifold $Y$ with fiber $F$, and $\widehat{HFK}(Y,K,[F], g(F)-1;\mathbb Z/2\mathbb Z)$ has rank $r$, then the monodromy of $K$ is freely isotopic to a diffeomorphism with at most $r-1$ fixed points. This generalizes earlier work of Baldwin--Hu--Sivek and Ni. We also clarify a misleading formula in Cotton-Clay's computation of the symplectic Floer homology of mapping classes of surfaces.
