Binomial rings, and integral homology of complements of compact toric arrangements

Alexey G. Gorinov, Alexander V. Zakharov

An \emph{affine subtorus} of the compact torus $T=(S^1{)}^n$ is a translated copy of a Lie subgroup. Given a finite collection $T_1,\dots ,T_k$ of such subtori, and a prime $p$, we…
