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…
Flat Affine Manifolds And Their Transformations
A. Medina, O. Saldarriaga, A. Villabon
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 preserv…
New Characterization of Flat Affine Manifolds and the Associative Envelope of a Left Symmetric Algebra
Alberto Medina, Omar Saldarriaga, Andres Villabón
This paper deals with affine connections on real manifolds. We give a new characterization of flat affine connections on real manifolds by means of certain affine representations o…
Flat Affine or Projective Geometries on Lie Groups
Alberto Medina, Omar Saldarriaga, Hernan Giraldo
This paper deals essentially with affine or projective transformations of Lie groups endowed with a flat left invariant affine or projective structure. These groups are called flat…
A particular case of the Level increasing Conjecture for Type A fusion algebras
Omar Saldarriaga
A particular case of the level increasing conjecture for type A fusion coefficientes is proved for when one the weights is a multiple of the first fundamental weight.
Fusion algebras, symmetric polynomials, orbits of N-groups, and rank-level duality
Omar Saldarriaga
A method of computing fusion coefficients for Lie algebras of type on level was recently developed by A. Feingold and M. Weiner \cite{FW} using orbits of $\mathbb{Z}_…
