Abstract: The study of affine crystallographic groups has a long history which goes back to Hilbert's 18th problem. More precisely Hilbert (essentially) asked if there is only a finite number, up to conjugacy in The Auslander Conjecture. Every crystallographic subgroup In 1977 J. Milnor stated the following question: Question. Does there exist a complete affinely flat manifold We will explain ideas and methods, recent and old results related to the above problems.
