Abstract

We show that for any graph G, the proper part of the intersection poset of the corresponding graphical arrangement <TEX>$\mathcal{A}_G$</TEX> has the homotopy type of a wedge of spheres. Furthermore, we also indicate the number of spheres in the wedge, based on the number of spanning forests of G and other graphs that are obtained from G.
