โœฆ Synopsis


Every affine map between two affinely connected manifolds is the composition of an affine submersion and an affine immersion; and the inverse image of an autoparallel submanifold by such maps is the union of autoparallel submanifolds. Furthermore, the Lie group of all affine transformations of an affinely connected manifold carries the compact-open topology.

This note tries to decide which groups can occur as fundamental groups of complete afhnely flat manifolds. THEOREM 1.2. If a group is torsion-free and contains a polycylic subgroup of finite index, then it is isomorphic to the fundamental group TTJM) for some complete a&ely jut manifold M. For defi
