Abstract

Every $L$-space knot is fibered and strongly quasi-positive, but this does not hold for $L$-space links. In this paper, we use the so called H-function, which is a concordance link invariant, to introduce a subfamily of fibered strongly quasi-positive $L$-space links. Furthermore, we present an infinite family of $L$-space links which are not quasi-positive.

纤维和强拟正l -空间链路

每个$L$空间结都是纤维的，并且是强准正的，但这并不适用于$L$空间结。本文利用协调链路不变量h函数，引入了光纤强拟正$L$空间链路的一个子族。进一步，我们给出了一个无限的非拟正$L$空间链族。
