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

Understand

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.
