Abstract: We develop a theory of volume polynomials of generalized virtual polytopes based on the study of topology of affine subspace arrangements in a real Euclidean space. We apply this theory to obtain a topological version of the Bernstein–Kushnirenko theorem as well as Stanley–Reisner and Pukhlikov–Khovanskii type descriptions for the cohomology rings of generalized quasitoric manifolds.

Keywords: quasitoric manifold, star-shaped sphere, virtual polytope, multi-fan, multi-polytope, moment–angle complex, Stanley–Reisner ring.
