Abstract: (arXiv)
A simple model of the brane-world cosmology has been proposed, which is characterized by four parameters, the bulk cosmological constant, the spatial curvature of the universe, the radiation strength arising from bulk space-time and the breaking parameter of -symmetry. The bulk space-time is assumed to be locally static five-dimensional analogue of the Schwarzschild-anti-de Sitter space-time, and then the location of three-brane is determined by metric junction. The resulting Friedmann equation recovers standard cosmology, and a new term arises if the assumption -symmetry is dropped, which behaves as cosmological term in the early universe, next turns to negative curvature term, and finally damps rapidly.- cosmological model
