An orbifold approach to black and white crystallographic groups
Given a crystallographic space group G , Bonahon and Siebenmann show in [B + SI] that it can be thought of as the fundamental group of a closed 3-orbifold Q which, because in most cases G preserves some direction V in 1R , usually admits an S1-fibration over a 2-orbifold B : we write (IR3,V)/G = Q -...
