非临界Einstein-Weyl引力与AdS/CFT Correspondence

Noncritical Einstein-Weyl Gravity and the AdS/CFT Correspondence

Seungjoon Hyun, Wooje Jang, Jaehoon Jeong, Sang-Heon Yi

摘要:

我们探讨四维爱因斯坦-外尔引力和反德西特时空的超引力。对于一个特定的范围内的耦合与适当的边界条件,我们证明了有效的等效理论与爱因斯坦引力和AdS超引力在二次拉格朗日水平。此外,我们表明,这些等价可以提升到全非线性水平。我们还证明了对于广义Gibbons-Hawking项也有类似的行为。由此我们发现,Einstein-Weyl引力和超引力的对偶共形场论中的关联函数可以很容易地从Einstein引力和AdS超引力的相应关联函数中读出。对临界引力和超引力以及共形引力和超引力中的一些问题也作了评述。

英文摘要:

We explore four-dimensional Einstein-Weyl gravity and supergravity on anti-de Sitter spacetime. For a specific range of the coupling with appropriate boundary conditions, we show the effective equivalence of the theory with Einstein gravity and AdS supergravity at the quadratic Lagrangian level. Furthermore we show that these equivalences can be promoted to the full nonlinear level. We also show that the similar behavior holds for the generalized Gibbons-Hawking terms. From this we find that the correlation functions in the dual conformal field theory of Einstein-Weyl gravity and supergravity can be readily read off from corresponding ones from Einstein gravity and AdS supergravity. We also give comments on some issues in critical gravity and supergravity as well as conformal gravity and supergravity.
