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.
The work of the first author was performed within the framework of the HSE University Basic Research Program. The third author was supported in part by the Canadian Grant no. 156833-17.
