In this paper we explain how an arithmetical invariant for G- cover - we call the base invariant - provides a stratification of Hurwitz moduli spaces of G-covers of the pro jective line by closed subvarieties. This strati- ...Read more >
In this paper we explain how an arithmetical invariant for G- cover - we call the base invariant - provides a stratification of Hurwitz moduli spaces of G-covers of the pro jective line by closed subvarieties. This strati- fication geometrically encodes arithmetical properties of Hurwitz spaces.Read less <
