Title: Fibered links, singularities and branched covers

Abstract:
A link in the 3-sphere is called fibered if its complement can be filled
with disjoint orientable surfaces whose boundary is the link. Fibered
links arise in different contexts, for example as links of singularities
of polynomial maps from $\mathbb{R}^4$ to $\mathbb{R}^2$. Furthermore, for a simple
branched covering map $\pi:S^3\to S^3$ branched over a link $L$ the
preimage $\pi^{-1}(\alpha)$ of any braid axis $\alpha$ for $L$ is a
fibered link. In this talk I am going to discuss both of these topics
(singularities and branched covers) and how they could be related.
