Chow Motive of Fulton-MacPherson configuration spaces and wonderful compactifications

Algebraic Geometry 2019-11-01 v2

Abstract

We study the Chow groups and the Chow motives of the wonderful compactifications YGY_{\mathcal{G}} of arrangements of subvarieties. We prove a natural decomposition of the Chow motive of YGY_\mathcal{G}, in particular of the Fulton-MacPherson configuration space X[n]X[n]. As a consequence, we prove a decomposition of the Chow motive of X[n]/SnX[n]/\frak{S}_n. A generating function for the Chow groups and for the Chow motive of X[n]X[n] is given.
