| Abstract: | We extend the Billera–Ehrenborg–Readdy map between the intersection lattice and face lattice of a central hyperplane arrangement to affine and toric hyperplane arrangements. For arrangements on the torus, we also generalize Zaslavsky’s fundamental results on the number of regions. |
| Keywords: | The cd-index The complex of unbounded regions Flag enumeration Manifolds The toric Zaslavsky invariant The n-dimensional torus |
