Cosmological applications of space-time torsion 

Francisco Cabral




In this talk i will make a brief review on the basics of gravitational theories with torsion with special focus on the Einstein-Cartan-Sciama-Kibble theory and its cosmological applications. Most cosmological applications of torsion theories consist in allowing the existence of cosmic acceleration without any kind of dark energy, however, we will see that the Einstein-Cartan theory applied to spatially homogeneous and isotropic models provides an interesting path to solve many other problems in cosmology such as, for example, the singularity problem, the matter/anti-matter asymmetry, dark matter, the flatness and horizon problems (without inflation). I will try to show the potential importance of gravity theories with torsion in cosmology (and astrophysics) and briefly expose some other issues such as experimental tests of space-time torsion.
