The role of torsion in projective invariant theories of gravity with non-minimally coupled matter fields
V. I. Afonso, Cecilia Bejarano, Jose Beltran Jimenez +2
We study a large family of metric-affine theories with a projective symmetry, including non-minimally coupled matter fields which respect this invariance. The symmetry is straightf…

Scalar geons in Born-Infeld gravity
V. I. Afonso, Gonzalo J. Olmo, D. Rubiera-Garcia
The existence of static, spherically symmetric, self-gravitating scalar field solutions in the context of Born-Infeld gravity is explored. Upon a combination of analytical approxim…
