Abstract
We analyze solutions of Chamseddine’s topological gravity in four-dimensional spacetime and discover various black hole solutions, with and without torsion, as well as solutions that describe naked singularities. Since all the solutions belong to the sector with vanishing scalar fields, they share the peculiar trait that all conserved charges are zero. Published by the American Physical Society2025
