Modular equalities for complex reflection arrangements

Daniela Anca Macinic, Stefan Papadima, Clement Radu Popescu

We compute the combinatorial Aomoto-Betti numbers ${\beta }_p(\mathcal{A})$ of a complex reflection arrangement. When $\mathcal{A}$ has rank at least $3$, we find that $β_p(\mathcal{A})\l…
