Two-boundaries AdS/CFT correspondence in dilatonic gravity

We discuss dilatonic gravity (bulk theory) from the point of view of (gener alized) AdS/CFT correspondence. Self-consistent dilatonic background is con sidered. It may be understood as two boundaries space where AdS boundary ap pears as infinite boundary and new (singular) boundary occurs at short dist ances. The two-point correlation function and conformal dimension for minim al and dilaton coupled scalar are found. Even for minimal scalar, the confo rmal dimension is found to be different on above two boundaries. Hence, new CFT appears in AdS/CFT correspondence at short distances. AdS/CFT correspo ndence may be understood as interpolating bulk theory between two different CFTs. (C) 1999 Elsevier Science B.V, All rights reserved.
