Title: A topological origin for Dark Energy

J. Lorca Espiro, Morgan Le Delliou (IFT-UNESP)

Comments: The problem presented is ill-defined and therefore the solutions are not consistent as claimed. First, the variational problem is not redefined after the characteristic classes are added into the action, which is necessary. Secondly, the paper assumes certain restrictions over the contortion that forces the topology in a very cumbersome way which is, as we see it, still very poorly justified
