چکیده
We analyze the conformal invariance of submanifold observables associated with k-branes in the AdS/CFT correspondence. For odd k, the resulting observables are conformally invariant, and for even k, they transform with a conformal anomaly that is given by a local expression which we analyze in detail for k = 2.

AdS/CFT Correspondence And Topological Field Theory
In N = 4 super Yang-Mills theory on a four-manifold M , one can specify a discrete magnetic flux valued in H 2 (M, Z N). This flux is encoded in the AdS/CFT correspondence in terms of a five-dimensional topological field theory with Chern-Simons action. A similar topological field theory in seven dimensions governs the space of " conformal blocks " of the six-dimensional (0, 2) conformal field ...

Asymptotically de Sitter dilatonic space-time, holographic RG flow and conformal anomaly from (dilatonic) dS/CFT correspondence ABSTRACT The number of asymptotically de Sitter (non-singular) solutions of 5d dilatonic gravity with positive cosmological constant is found. These solutions are similar to the previously known asymptotically AdS spaces where dilaton may generate the singularity. Usin...
متن کاملConformal anomaly from dS / CFT correspondence
In frames of dS/CFT correspondence suggested by Strominger we calculate holographic conformal anomaly for dual euclidean CFT. The holographic renormalization group method is used for this purpose. It is explicitly demonstrated that two-dimensional and four-dimensional conformal anomalies (or corresponding central charges) have the same form as those obtained in AdS/CFT duality.

متن کاملSuperconformal Anomaly from Ads/cft Correspondence †
For a classical superconformal gauge theory in a conformal supergravity background, its chiral R-symmetry anomaly, Weyl anomaly and super-Weyl anomaly constitute a supermultiplet. We review how these anomalies arise from the five-dimensional gauged supergravity in terms of the AdS/CFT correspondence at the gravity level. The holographic production of this full superconformal anomaly multiplet p...
متن کاملConformal Triality of De Sitter, Minkowski and Anti-de Sitter Spaces
We describe how conformal Minkowski, dSand AdS-spaces can be united into a single submanifold [N ] of RP . It is the set of generators of the null cone in M. Conformal transformations on the Mink-, dSand AdS-spaces are induced by O(2, 4) linear transformations on M. We also describe how Weyl transformations and conformal transformations can be resulted in on [N ]. In such a picture we give a de...
