多维Gauss-Bonnet宇宙学幂律解的稳定性

On stability of power-law solution in multidimensional Gauss-Bonnet cosmology

D. M. Chirkov, A. V. Toporensky

摘要:

本文研究在均匀磁场存在下,在高斯-邦尼引力中的平坦各向异性多维宇宙模型的动力学。特别是,我们发现的条件下,已知的幂律真空解决方案可以是一个吸引子的情况下,非零磁场。我们还描述了一类特殊的数值解$(5+1)$维的情况下,不接近幂律制度。

英文摘要:

We consider dynamics of a flat anisotropic multidimensional cosmological model in Gauss-Bonnet gravity in the presence of a homogeneous magnetic field. In particular, we find conditions under which the known power-law vacuum solution can be an attractor for the case with non-zero magnetic field. We also describe a particular class of numerical solution in $(5+1)$-dimensional case which does not approach the power-law regime.
