Time-Machines Construct in $f (R, A, A^{μν} A_{μν})$ and $f (R)$ Modified Gravity Theories

F. Ahmed, J. C. R. de Souza, A. F. Santos

In this paper, our objective is to explore a time-machine space-time formulated in general relativity, as introduced by Li (Phys. Rev. D {\bf 59}, 084016 (1999)), within the contex…

An axially symmetric spacetime with causality violation in Ricci-inverse gravity

J. C. R. de Souza, A. F. Santos

In this paper, Ricci-inverse gravity is investigated. It is an alternative theory of gravity that introduces into the Einstein-Hilbert action an anti-curvature scalar that is obtai…
