Friedmann-like universes with torsion
D Kranas, CG Tsagas, JD Barrow, D Iosifidis - The European Physical …, 2019 - Springer
We consider spatially homogeneous and isotropic cosmologies with non-vanishing torsion,
which assumes a specific form due to the high symmetry of these universes. Using covariant …

What is a singular black hole beyond General Relativity?
Exploring the characterization of singular black hole spacetimes, we study the relation
between energy density, curvature invariants, and geodesic completeness using a quadratic …
