具有理想流体源的N维平面对称解

N-dimensional plane symmetric solution with perfect fluid source

Hongsheng Zhang, Hyerim Noh

摘要:

在最近的工作中,我们发现了一类新的由理想流体引起的平面对称解。研究了由理想流体源产生的爱因斯坦场方程的n维($n\geq 4$)整体平面对称解,它是我们以前的4维解的直接推广.在该解中允许一个类时Killing向量和$(n-2)(n-1)/2$类空Killing向量,它们跨越欧几里得群$G_{(n-2)(n-1)/2}$。研究了弱能、强能和主导能条件对源参数的约束范围。分别分析了与n维Taub度量和Minkowski度量相匹配的边界条件。

英文摘要:

A new class of plane symmetric solution sourced by a perfect fluid is found in our recent work. An n-dimensional ($n\geq 4$) global plane symmetric solution of Einstein field equation generated by a perfect fluid source is investigated, which is the direct generalization of our previous 4-dimensional solution. One time-like Killing vector and $(n-2)(n-1)/2$ space-like Killing vectors, which span a Euclidean group $G_{(n-2)(n-1)/2}$, are permitted in this solution. The regions of the parameters constrained by weak, strong and dominant energy conditions for the source are studied. The boundary condition to match to n-dimensional Taub metric and Minkowski metric are analyzed respectively.
