The shear dynamics in Bianchi I cosmological model on the brane

Abstract

The shear dynamics in Bianchi I cosmological model on the brane with a perfect fluid (the equation of state is $p=(\gamma -1)\mu$) is studied. It is shown that for $1<\gamma <2$ the shear parameter has maximum at some moment during a transition period from nonstandard to standard cosmology. An exact formula for the matter density $\mu$ in the epoch of maximum shear parameter as a function of the equation of state is obtained.
