AdSS_5 Brane World Cosmology

Abstract

The gravitational equations of the 5-dimensional analogue of the AdSS space-time, where all the matter fields are confined on the 3-brane are examined. The most general solutions are established in the generic case of a non-Z_2-symmetric bulk. Constraining these solutions we derive a number of remarkable metrics widely investigated in the literature. Finally, we make many important conclusions about the viability of the presented scenario and cosmology.Comment: JHEP file, 8 pages, v5: Corrected typo
