The aim of this paper is to classify non-conformally flat static plane symmetric (SPS) perfect fluid solutions via proper conformal vector fields (CVFs) in [Formula: see text] gravity. For this purpose, first we explore some SPS perfect fluid solutions of the Einstein field equations (EFEs) in [Formula: see text] gravity. Second, we utilize these solutions to find proper CVFs. In this study, we found 16 cases. A detailed study of each case reveals that in three of these cases, the space-times admit proper CVFs whereas in the rest of the cases, either the space-times become conformally flat or they admit proper homothetic vector fields (HVFs) or Killing vector fields (KVFs). The dimension of CVFs for non-conformally flat space-times in [Formula: see text] gravity is four, five or six.

非共形平面静态平面对称完美流体解的分类通过适当的共形矢量场在 f(T) 重力

本文的目的是通过 [公式:见文本] 重力中的适当保形矢量场 (CVF) 对非保形平面静态平面对称 (SPS) 完美流体解进行分类。为此,首先我们在[公式:见正文]重力中探索爱因斯坦场方程(EFE)的一些SPS完美流体解。其次,我们利用这些解决方案找到合适的 CVF。在这项研究中,我们发现了 16 例。对每个案例的详细研究表明,在其中三个案例中,时空允许适当的 CVF,而在其余案例中,时空要么变得共形平坦,要么它们允许适当的同位向量场 (HVF) 或 Killing 向量字段(KVF)。[公式:见正文]重力中非共形平坦时空的 CVF 维数是四、五或六。
