Black Hole Persistence in New General Relativity
Balkar Yildirim, Alan Albert Coley, Diego Fernando López
We investigate whether black holes can persist through the bounce with a minimal scale factor in a non-singular cosmology, whereby black holes from a previous contracting phase sur…

De Sitter-Invariant Black Holes
D. F. López, S. Abarghouei Nejad, José G. Pereira
In the de Sitter-invariant approach to gravitation, all solutions to the gravitational field equations are spacetimes that reduce locally to de Sitter. Consequently, besides includ…

On black holes in teleparallel torsion theories of gravity
Alan A. Coley, Nicholas T. Layden, Diego F. Lopez
We first present an overview of the Schwarzschild vacuum spacetime within general relativity, with particular emphasis on the role of scalar polynomial invariants and the null fram…
