On the causality aspects of the dynamical Chern-Simons modified gravity
P. J. Porfirio, J. B. Fonseca-Neto, J. R. Nascimento +1
We discuss the Gödel-type solutions within the dynamical Chern-Simons modified gravity in four dimensions. Within our study, we show that in the vacuum case the causal solutions ar…
Chern-Simons modified gravity and closed time-like curves
P. J. Porfirio, J. B. Fonseca-Neto, J. R. Nascimento +3
We verify the consistency of the Gödel-type solutions within the four-dimensional Chern-Simons modified gravity with the non-dynamical Chern-Simons coefficient, for different forms…
Gödel and Gödel-type universes in Brans-Dicke theory
J. A. Agudelo, J. R. Nascimento, A. Yu. Petrov +2
In this paper, conditions for existence of Gödel and Gödel-type solutions in Brans-Dicke (BD) scalar-tensor theory and their main features are studied. The consistency of equations…
