On the Fundamental Group of the Complement of a Complex Hyperplane Arrangement
G. L. Rybnikov National Research University "Higher School of Economics"
Abstract:
We construct two combinatorially equivalent line arrangements in the complex projective plane such that the fundamental groups of their complements are not isomorphic. The proof uses a new invariant of the fundamental group of the complement to a line arrangement of a given combinatorial type with respect to isomorphisms inducing the canonical isomorphism of the first homology groups.
Keywords:
hyperplane arrangement, matroid, homology groups, fundamental group, lower central series.
