De Sitter-like configurations with asymptotic quintessence environment
Roberto Giambò, Orlando Luongo
We examine a spherically-symmetric class of spacetimes carrying vacuum energy, while considering the influence of an external dark energy environment represented by a non-dynamical…

Repulsive gravity in regular black holes
Orlando Luongo, Hernando Quevedo
We evaluate the effects of repulsive gravity using first order geometric invariants, \textit{i.e.}, the Ricci scalar and the eigenvalues of the Riemann curvature tensor, for three…
