There has been considerable interest in the past in analyzing specific families of hyperplane arrangements from the perspective of freeness. Examples of such families have primarily included classes of subarrangements of Coxeter arrangements. The subarrangements of the braid arrangement An, the Weyl arrangement of type An−1, are known as the graphical arrangements. They correspond naturally to graphs on n vertices. It follows mainly from the work of Stanley [14] and is recorded in [5, §3] that… CONTINUE READING
