2026-03-11 Baiting Xie Topology and Combinatorics of Complex Hyperplane Arrangement Complements In this talk, I will introduce which topological invariants of hyperplane arrangement complements are combinatorially determined. I will briefly sketch the proof of the classical result by Orlik and Solomon on the integral cohomology, and present some conjectures and recent progress on cohomology with local coefficients.
