Spherically symmetric solutions in four-dimensional Poincaré gravity with non-trivial torsion
arXiv:gr-qc/9704035 · doi:10.1088/0264-9381/15/2/005
Abstract
We study a four-dimensional gauge theory of the Poincaré group with topological action which generalizes some well-known two-dimensional gravity models. We classify the spherically symmetric solutions and discuss the perturbative propagation of excitations around flat spacetime.
