Crystallographic teams are teams which act in a pleasant means and through isometries on a few n-dimensional Euclidean area. They acquired their identify, simply because in 3 dimensions they take place because the symmetry teams of a crystal (which we think to increase to infinity in all directions). The publication is split into elements. within the first half, the elemental concept of crystallographic teams is constructed from the very starting, whereas within the moment half, extra complicated and newer subject matters are mentioned. So the 1st a part of the e-book can be usable as a textbook, whereas the second one half is extra attention-grabbing to researchers within the box. There are brief introductions to the topic sooner than each bankruptcy. on the finish of this booklet is an inventory of conjectures and open difficulties. in addition there are 3 appendices. The final one provides an instance of the torsion unfastened crystallographic staff with a trivial middle and a trivial outer automorphism group.

This quantity omits issues approximately generalization of crystallographic teams to nilpotent or solvable international and classical crystallography.

we wish to emphasize that the majority theorems and evidence awarded within the moment half are from the final 20 years. this can be after the publication of L Charlap “Bieberbach teams and flat manifolds” was once published.
