Abstract

We give a new combinatorial description of the cohomology ring structure of H^*(M(A);ℤ) of the complement M(A) of a real complexified toric arrangement A in (ℂ^*)^d. In particular, we correct an error in the paper ``The integer cohomology algebra of toric arrangements'', Adv. Math., 2017.
