论文摘要
我们研究了在\ cite {gbn}中引入的模型中，单独的高斯 - 邦网术语会在晚期四维FLRW时空中产生宇宙加速度和超级加速度。我们还讨论了从减速到加速和加速到超级加速的过渡。我们表明，高斯 - 骨网不变可以在低红移中驱动加速度，前提是其正则化系数的顺序与降低的普朗克质量与哈勃参数的比率相同。
We study the possibility that in the model introduced in \cite{GBN}, the Gauss-Bonnet term alone gives rise to the cosmic acceleration and super-acceleration in four-dimensional FLRW space-time at the late time. We also discuss transitions from deceleration to acceleration and acceleration to super-acceleration. We show that the Gauss-Bonnet invariant can drive the acceleration in the low redshift provided that its regularized coefficient has the same order as the squared of the ratio of the reduced Planck mass to the Hubble parameter.
