dc.descriptionCurrent universe (assumed here to be normal matter on the brane) is pressureless from observations. In this case the energy condition is $ρ_0\geq0$ and $p_0=0$. By using this condition, brane models can be distinguished. Then, assuming arbitrary component of matter in DGP model, we use four known energy conditions to study the matter on the brane. If there is nonnormal matter or energy (for example dark energy with $w<-1/3$) on the brane, the universe is accelerated.
