Brane world inflation induced by quantum effects

We consider a brane-world universe where an arbitrary large N quantum CFT is living on the domain wall. This corresponds to the implementation of a Randall-Sundrum compactification within the context of AdS/CFT correspondence. Using the anomaly induced effective action for the domain wall CFT the possibility of a self-consistent quantum creation of the 4d de Sitter wall Universe (inflation) is demonstrated, In case of the maximally SUSY Yang-Mills theory the exact correspondence with radius and effective tension found by Hawking-Hertog-Reall is obtained. The hyperbolic wall Universe may be induced by quantum effects only for exotic matter (higher derivatives conformal scalar) which has unusual sign of the central charge.
