Transformation groups of certain flat affine manifolds
O. Saldarriaga, A. Flórez
In this paper we characterize the group of affine transformations of a flat affine simply connected manifold whose developing map is a diffeomorphism. This is proved by making use…

The group of affine transformations of homogeneous spaces with discrete isotropy
O. Saldarriaga, A. Flórez
We present a method to compute the group of affine transformations of a homogeneous -space under specific conditions: when the group and the homogeneous -space admit line…
