Some solutions with torsion in Chern-Simons gravity and observable effects. (English) Zbl 1173.83018

An analogy between the BPS states in field theory and gravitational models with torsion is presented, and a method is discussed to construct solutions of Chern-Simons gravitational theories with torsion from solutions without torsion.
