On the Chow ring of the Hurwitz space of degree three covers of ${\bf P}^{1}$ (1505.04323v2)
Published 16 May 2015 in math.AG
Abstract: We determine that the Chow ring (with ${\bf Q}$-coefficients) of the Hurwitz space parametrizing degree three covers of ${\bf P}{1}$ is tautological. We also compute the rational Picard groups of auxiliary spaces of degree three maps with special marked points.
