Dilatonic quantum muli-brane-worlds - art. no. 084016

A five-dimensional dilatonic gravity action with surface counterterms motiv ated by AdS/CFT (conformal fluid theory) correspondence and with contributi ons of brane-quantum CFTs is considered around an AdS-like bulk. The effect ive equations of motion are constructed. They admit two (outer and inner), or multi-brane, solutions where the brane CFTs may be different. The role o f quantum-brane CFT is in inducing a complicated brane dilatonic gravity. F or exponential bulk potentials the number of AdS-like bulk spaces is found in analytical form. The corresponding flat or curved (de Sitter or hyperbol ic) dilatonic two branes are created, as a rule, thanks to quantum effects. The observable early universe may correspond to an inflationary brane. The found dilatonic quantum two-brane-worlds usually contain a naked singulari ty but in a couple explicit examples the curvature is finite and a horizon (corresponding to wormholelike space) appears.
