Fundamental groups of line arrangements: Enumerative aspects
Alexander I. Suciu
This is a survey of some recent developments in the study of complements of line arrangements in the complex plane. We investigate the fundamental groups and finite covers of those…

Hall invariants, homology of subgroups, and characteristic varieties
Daniel Matei, Alexander I. Suciu
Given a finitely-generated group G, and a finite group Γ, Philip Hall defined δ_Γto be the number of factor groups of G that are isomorphic to Γ. We show how to compute the Hall in…

Higher homotopy groups of complements of complex hyperplane arrangements
Stefan Papadima, Alexander I. Suciu
We generalize results of Hattori on the topology of complements of hyperplane arrangements, from the class of generic arrangements, to the much broader class of hypersolvable arran…
