On stability of the Kasner solution in quadratic gravity
  We consider dynamics of a flat anisotropic Universe filled by a perfect fluid
near a cosmological singularity in quadratic gravity. Two possible regimes are
described -- the Kasner anisotropic solution and an isotropic "vacuum
radiation" solution which has three sub cases depending on whether the equation
of state parameter $w$ is bigger, smaller or equals to $1/3$. Initial
conditions for numerical integrations have been chosen near General Relativity
anisotropic solution with matter (Jacobs solution). We have found that for such
initial conditions there is a range of values of coupling constants so that the
resulting cosmological singularity is isotropic.
