Infinitesimmaly homogeneous manifolds with symplectic and almost contact structure groups
Carlos Alberto Marín Arango, Alejandro Pinilla Barrera
We study infinitesimally homogeneous affine manifolds with prescribed structure groups. First, for the real symplectic group , we prove that the co…

A simplified categorical approach to several Galois theories
David Blázquez-Sanz, Carlos A. Marín Arango, Juan Felipe Ruiz Castrillon
We discuss the concept of Galois structure and Galois epimorphism in a general setting. Namely, a Galois structure for an epimorphism in some category ${\mathcal C…

Infinitesimally homogeneous manifolds with prescribed structure groups
Carlos Alberto Marín Arango, David Blázquez-Sanz
We explore the class of triples (M, nabla, P) where M is a manifold, nabla is an affine connection in M and P is a G-structure in M. Inside this class there are infinitesimally hom…
