The internal zonotopal algebra of a hyperplane arrangement, introduced by Holtz and Ron and further studied by Lenz in the context of approximation theory. In the case of a hyperplane arrangement arising from a graph, we give an interpretation of this algebra as the cohomology ring of a certain configuration space. In particular, this points us to a canonical integral form for such algebras.

This is joint work with Colin Crowley, Galen Dorpalen-Barry, and Andre Henriques.
