A new AdS/CFT correspondence
Horatiu Nastase, Warren Siegel
We consider a geometric zero-radius limit for strings on , where the anti-de Sitter hyperboloid becomes the projective lightcone. In this limit the fifth dimension…
Propagators for p-forms in AdS_{2p+1} and correlation functions in the AdS_7/(2,0) CFT correspondence
Iosif Bena, Horatiu Nastase, Diana Vaman
In AdS_{2p+1} we construct propagators for p-forms whose lagrangians contain terms of the form A / d A. In particular we explore the case of forms satisfying ``self duality in odd…
The AdS-CFT correspondence, consistent truncations and gauge invariance
Horatiu Nastase, Diana Vaman
We give arguments for a conjecture made in a previous paper, that one has to use only the gauged sugra action for the calculation of correlators of certain operators via the AdS-CF…
On the nonlinear KK reductions on spheres of supergravity theories
Horatiu Nastase, Diana Vaman
We address some issues related to the construction of general Kaluza-Klein (KK) ansätze for the compactification of a supergravity (sugra) theory on a sphere . We first reprod…
