Brane world inflation induced by quantum effects

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