论文摘要

我们谈到了时空(ST-HOMESONOUS)Gödel-type指标中的同质性,即Cubic Galileon理论(一种特定类别的广义Galileon理论)。我们检查了此类空间的一致性,即在物理动机的物质含量上,即完美的流体和电磁场。在这种情况下,我们发现可允许的解决方案对立方加利昂理论的恒定耦合($ c_ {i} $)施加了约束,以确保一致性。另外,我们显示了真空完全因果溶液的存在。

We address the homogeneous in space and time (ST-homogeneous) Gödel-type metrics within the cubic galileon theory, a particular class of generalized galileon theories. We check the consistency of such spacetimes for a physically well-motivated matter content, namely, a perfect fluid and an electromagnetic field. In this scenario, we find that the admissible solutions impose constraints on the constant couplings ($c_{i}$'s) of the cubic galileon theory to ensure the consistency. Also, we show the existence of a vacuum completely causal solution.
