Abstract

We exhibit all spatially isotropic homogeneous Galilean spacetimes of dimension (n+1)>=4, including the novel torsional ones, as null reductions of homogeneous pp-wave spacetimes. We also show that the pp-waves are sourced by pure radiation fields and analyse their global properties.

从pp波到伽利略时空

我们展示了所有维度（n+1）>=4的空间各向同性齐次伽利略时空，包括新的扭转时空，作为齐次pp波时空的零约简。我们还证明了pp波是由纯辐射场产生的，并分析了它们的全局性质。
