On the fiberedness of surgery 3-manifolds

Yi Ni, Zhongzi Wang

Let $M$ be a closed orientable 3-manifold and $k$ be a knot in $M$ . Then the Dehn surgery of $M$ along $k$ with slope $I^\pm$ is not surface fibered for all but a sparse set of slopes…

Knot Floer homology and fixed points

Yi Ni

If $K$ is a fibered knot in a closed, oriented $3$ --manifold $Y$ with fiber $F$ , and $H F K (Y, K, [F], g (F) - 1; Z /2 Z)$ has rank $r$ , then the monodromy of $K$ i…

Generation of sutured manifolds

Yi Ni

Given a compact, oriented, connected surface $F$ , we show that the set of connected sutured manifolds $(M, I^^{3})$ with $R_{\pm} (I^^{3}) ≅ F$ is generated by the product sutured manifol…
