Crystallographic groups with trivial center and outer automorphism group
Published online by Cambridge University Press: 06 March 2017
Abstract
Let Γ be a crystallographic group of dimension n, i.e. a discrete, cocompact subgroup of Isom(ℝn) = O(n) ⋉ ℝn. For any n ⩾ 2, we construct a crystallographic group with a trivial center and trivial outer automorphism group.
