AI 中文摘要
我们推导了用于反弹聚合物量子化比安基-I时空的广义有效弗里德曼和瑞查德胡里方程。我们进一步证明，文献中数值推导的反弹时物质能量密度与各向异性切变之间的关系对于任何类型的物质内容都精确成立，并推导了该关系中出现的常数的显式表达式。
英文摘要
We derive generalized effective Friedmann and Raychaudhuri equations for a bouncing polymer quantized Bianchi-I spacetime. We further prove that the relation numerically derived in the literature between the matter energy density and the anisotropic shear at the bounce holds exactly for any type of matter content, and derive explicit expressions for the constants that appear in that relation.
