The shear dynamics in Bianchi I cosmological model on the brane

الأصل · EN

The shear dynamics in Bianchi I cosmological model on the brane with a perfect fluid (the equation of state is p=(γ-1) μ) is studied. It is shown that for 1 < γ< 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 μ in the epoch of maximum shear parameter as a function of the equation of state is obtained.
