Brane Universe and Standard Cosmology
Abstract
Brane cosmology takes the unconventional form $H\sim \sqrt{\rho}$. To recover the standard cosmology, we have to assume that the matter density is much less than the brane tension. We show that the assumption can be justified even near the end of inflation if we finetune the coupling constant of the inflaton potential. As a consequence, the standard cosmology is recovered after inflation.
