Title : A Cellular decomposition of the Fulton Mac Pherson operad
Abstract : We construct a cellular decomposition of the Axelrod- Singer-Fulton-MacPherson compactification of the con- figuration spaces in the plane, that is compatible with the operad composition. Cells are indexed by trees with bi-coloured edges, and vertices are labelled by cells of the cacti operad. This answers positively a conjecture by Kontsevich and Soibelman.
