The S_n action on the homology groups of M_{0,n}-bar

Abstract: The moduli space M_{0,n}-bar is a compactification of the space of configurations of n points on P^1. The symmetric group on n letters acts on M_{0,n}-bar, and thus on its (co-)homology groups. I will introduce M_{0,n}-bar, its (co-)homology groups, and the S_n action. This talk includes joint work with Rob Silversmith.
