Description
Holography(AdS/CFT correspondence) has proved to be quite useful in under-
standing field theory at the boundary from the information in the bulk and vice-
versa, the goal is to see if such a prescription can help us understand our universe
and provide a mapping between cosmology and a CFT defined on a manifold with
boundary(BCFT). The bulk geometry is taken to be AdS with an additional End-
Of-the-World (EOW) brane along with the asymptotic AdS boundary such that the
boundary in the dual BCFT theory corresponds to EOW brane on gravity. The ad-
vantage of this construction is that although the bulk geometry is taken to be AdS,
the space-time on the brane could be dS and thus could pave a way to study dS/CFT
by embedding in higher dimensional AdS/CFT.
First AdS3/BCFT2 is considered and matter fields (complex scalar) on the brane
are coupled to the gravitational dynamics of the AdS bulk, thus serving as potent
tools for cosmology. Then the analysis is extended to AdS5, to draw some conclusions
about our real world cosmology from branes with some big-bang like solutions.
