Causality Violating Solutions in Curvature-Squared Gravity
J. C. R. de Souza, A. F. Santos, R. Bufalo
In this paper, we consider some causality violating solutions in the curvature-squared gravity in order to examine whether closed timelike curves (CTCs) are allowed in these models…

Cosmological constant Petrov type-N space-time in Ricci-inverse gravity
F. Ahmed, J. C. R. de Souza, A. F. Santos
Our focus is on a specific type-N space-time that exhibits closed time-like curves in general relativity theory within the framework of Ricci-inverse gravity model. The matter-ener…

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…
