Cosmological solutions in the brane-bulk system
In this work we find cosmological solutions in the brane-bulk system starting
from a 5-D line element which is a simple extension, for cosmological
applications, of the pioneering Randall-Sundrum line element. From the
knowledge of the bulk metric, assumed to have the form of plane waves
propagating in the fifth dimension, we solve the corresponding 4-D Einstein
equations on the brane with a well defined energy-momentum tensor.Comment: 14 pages, revtex4, comments adde
