https://doi.org/10.1007/978-94-007-7500-8n some wonderful results in riemannian geometry which, after a little initial work, come free with the algebraic results on Bieberbach groups. This procedure in which problems in one field, riemannian geometry, are converted to problems in another field, algebra, is very much in the spirit of modern

Barbara Zambelli,Stefano CiurliWe have defined Bieberbach subgroups of M. as the torsionfree, discrete, uniform ones. We have seen that such a subgroup . contains a free abelian subgroup . ⋂ IR. which is normal, maximal abelian, and of finite index in .. We now define what it means for an abstract group to be Bieberbach.
