在带有高斯-博内项的扩展爱因斯坦理论的框架内研究了具有两个空间平坦子空间的真空中的高维宇宙学解决方案。发现初始奇点是可以消除的。子流形的两个尺度在早期迅速产生较大差异。在后期阶段，模型宇宙接近更高维的卡斯纳解。
Higher dimensional cosmological solutions in vacuum with two spatially flat subspaces are studied in the framework of the extended Einstein theory with the Gauss-Bonnet term. It is found that the initial singularity can be eliminated. A large discrepancy of the two scales of the submanifolds is produced rapidly in the early stage. In the later stage the model universe approaches to a higher dimensional Kasner solution.
