Hurwitz components of groups with socle PSL (3; q)

Abstract

For a finite group G, the Hurwitz space Hinr,g(G) is the space of genus g covers of the Riemann sphere ℙ1 with r branch points and the monodromy group G. In this paper, we give a complete list of some almost simple groups of Lie rank two. That is, we assume that G is a primitive almost simple groups of Lie rank two. Under this assumption we determine the braid orbits on the suitable Nielsen classes, which is equivalent to finding connected components in Hinr,g(G).
