is AdS-Schwarzschild or Reissner-Nordstr"om AdS. From the point of view of a homogeneous and isotropic brane we see quadratic deviations from the FRW equations of the standard cosmology. The radiation comes from a field theory that is dual to the AdS bulk. We also develop a new approach which allows us to consider branes that are not near the AdS boundary. This time the dual field theory contributes quadratic energy density/pressure terms to the FRW equations. For the AdS-Schwarzschild case, we show that the geometry on a brane near the AdS boundary is just that of a radiation dominated FRW universe. We examine the Einstein equations induced on a general (n-2)-brane of arbitrary tension, embedded in some n-dimensional bulk. We also derive the general equations of motion for a braneworld containing a domain wall. We also show how to construct instantons on the brane, and calculate the probability of false vacuum decay. The brane energy-momentum tensor enters these equations both linearly and quadratically.
In this dissertation we will use CMB data, together with the other. Multi-field inflationary models 487 and Brane Inflation 483.
Authors: Antonio Padilla (Submitted on ( v1 last revised (this version, v2). Which authors of this paper are endorsers? For the critical brane, the induced geometry is identical to that of a vacuum domain wall in (n-1)-dimensional Einstein gravity. We develop the tools to construct a nested Randall-Sundrum scenario whereby we have a critical' domain wall living on an anti-de Sitter brane. This contribution can be understood holographically. There is also a contribution from a bulk Weyl tensor. Remarkably, these take exactly the same form as for additional matter placed on the brane by hand, with no bulk Weyl tensor.
