Towards the homology of Hurwitz spaces. (English) Zbl 0848.14005

The purpose of this paper is to construct a complex which computes the homology of Hurwitz spaces of branched covers of \(\mathbb{P}^1\). We also compute some of the low dimensional homology groups of a compactification of the Hurwitz space, and report on computer calculations performed in specific examples.
