On the Center of the Fundamental Group of the Complement of a Hyperplane ArrangementRaul CordovilDep. de Matemática, I.S.T. and C.M.A.F.-U.L.,Av. Prof. Gama Pinto, 2, 1699 Lisboa Codex - PORTUGAL Abstract: Let ${\cal A}$ be a simplicial hyperplane arrangement in ${{\bf R}^d}$. We prove that the center of the fundamental group of the manifold ${\bf C}^d\backslash\bigcup\{{H\otimes {\bf C}}: H\in {\cal A\}}$ is a direct product of infinite cyclic subgroups.
