Geometrical description of spin-2 fields
arXiv:gr-qc/0212026
Abstract
We show that the torsion of a Cartan geometry can be associated to two spin-2 fields. This structure allows a new approach to deal with the proposal of geometrization of spin-2 fields besides the traditional one dealt with in General Relativity. We use the associated Hilbert-Einstein Lagrangian for generating a dynamics for the fields.
