论文摘要
重力的regge-teitelboim公式，利用动态嵌入在背景空间中，有效地在标准的爱因斯坦方程中引入了源术语，而这些源术语不可归因于能量momentum张量。我们表明，对于Robertson-Walker指标的一类简单类别的嵌入，这些源术语自然会产生宇宙加速。
The Regge-Teitelboim formulation of gravity, which utilizes dynamical embeddings in a background space, effectively introduces source terms in the standard Einstein equations that are not attributable to the energy-momentum tensor. We show that for a simple class of embeddings of the Robertson-Walker metric, these source terms naturally generate cosmic acceleration.
