打结手术中的Lefschetz纤维化$4$ -通过Stallings扭曲的歧管

Lefschetz fibrations on knot surgery $4$-manifolds via Stallings twist

Jongil Park, Ki-Heon Yun

摘要:

本文构造了一类纽结外科$4$ -流形,它允许任意多个具有相同亏格的非同构Lefschetz纤维化结构。我们得到这样的家庭进行结手术的椭圆形表面$E(2)$使用连接的总和纤维结Stallings扭曲从切片结$3_1 \sharp 3^*_1$。通过比较它们由相应的单值分解导出的单值群,我们证明了它们具有互不同构的Lefschetz纤维化结构。

英文摘要:

In this article we construct a family of knot surgery $4$-manifolds admitting arbitrarily many nonisomorphic Lefschetz fibration structures with the same genus fiber. We obtain such families by performing knot surgery on an elliptic surface $E(2)$ using connected sums of fibered knots obtained by Stallings twist from a slice knot $3_1 \sharp 3^*_1$. By comparing their monodromy groups induced from the corresponding monodromy factorizations, we show that they admit mutually nonisomorphic Lefschetz fibration structures.
