所有Killing向量均为Poincaré代数的新几何

New Geometry with All Killing Vectors Spanning the Poincaré Algebra

Chao-Guang Huang, Yu Tian, Xiao-Ning Wu, Zhan Xu, Bin Zhou

摘要:

提出了Killing向量跨越Poincaré代数的新四维几何,并分析了其结构.这种新的几何可以看作是具有负宇宙学常数的真空爱因斯坦场方程的退化延拓的庞加莱不变解,并提供了一个具有罗巴切夫斯基空间的静态宇宙时空.讨论了自由粒子在时空中的运动。

英文摘要:

The new 4D geometry whose Killing vectors span the Poincaré algebra is presented and its structure is analyzed. The new geometry can be regarded as the Poincaré-invariant solution of the degenerate extension of the vacuum Einstein field equations with a negative cosmological constant and provides a static cosmological space-time with a Lobachevsky space. The motion of free particles in the space-time is discussed.
