We consider asymptotic solution near a singularity, condition for inflation and bounces and some detail of chaotic behavior in the brane model. Each results are compared with those known in the standard cosmology.13 pages with 2 eps figures, submitted to Astronomy LettersGeneral Relativity and Quantum Cosmologytext
