Spacetime deformations and inhomogeneous universes |
I define the concept of spacetime deformations as n extension of conformal transformations. Deformations are a covariant way to relate different metrics and therefore different geometries. In particular I show how one can describe a inhomogeneous cosmological model by deforming an exact solution like the FLRW and try to study its physical implications. |

F(R) theories with torsion |
I present the F(R) theories with torsion. I discuss their mathematical formulation, the nature of torsion in these theories and their relation with a particular Brans-Dicke theory. A comparison with the F(R) theories with torsion is made. Finally I present a cosmological model in these theories. |
