    Transformation groups of certain flat affine manifolds

    In this paper we characterize the group of affine transformations of a flat affine simply connected manifold whose develo** map is a diffeomorphism. This is proved by making use of some simple facts about ho...

    Flat affine manifolds and their transformations

    We give a characterization of flat affine connections on manifolds by means of a natural affine representation of the universal covering of the Lie group of diffeomorphisms preserving the connection. From the ...
