关于CFT维数间隙的上界

On Upper Bounds in Dimension Gaps of CFT's

Tristan C. Collins, Daniel Jafferis, Cumrun Vafa, Kai Xu, Shing-Tung Yau

摘要:

我们认为CFT的膜探测内部流形的奇点。我们主要讨论了具有内部空间的全息模型,包括来自CY的任意Sasaki-Einstein流形以及任意球流形。在所有这些情况下,我们表明,有一个普遍的上限(仅取决于时空维度)的共形维度的第一个非平凡的自旋2运营商在对偶CFT和最小直径(在AdS单位)的内部空间的全息对偶和猜想,它持有所有CFT的。

英文摘要:

We consider CFT's arising from branes probing singularities of internal manifolds. We focus on holographic models with internal space including arbtirary Sasaki-Einstein manifolds coming from CY as well as arbitrary sphere quotients. In all these cases we show that there is a universal upper bound (depending only on the spacetime dimension) for the conformal dimension of the first non-trivial spin 2 operator in the dual CFT and a minimal diameter (in AdS units) for the internal space of the holographic dual and conjecture it holds for all CFT's.
