A generalization of several classical invariants of links [PDF]

, 2006
We extend several classical invariants of links in the 3-sphere to links in so-called quasi-cylinders. These invariants include the linking number, the Seifert form, the Alexander module, the Alexander-Conway polynomial and the Murasugi-Tristram-Levine ...

Alexander Modules [PDF]

Proceedings of the American Mathematical Society, 1984
The Alexander modules of a link are the homology groups of the universal abelian cover of the complement of the link. For a link of n n -spheres in S n + 2 {S^{n + 2}} , we show that, if n ⩾ 2 n \geqslant 2

Branched covers of quasipositive links and L-spaces

, 2019
Let $L$ be a oriented link such that $\Sigma_n(L)$, the $n$-fold cyclic cover of $S^3$ branched over $L$, is an L-space for some $n \geq 2$. We show that if either $L$ is a strongly quasipositive link other than one with Alexander polynomial a multiple ...
