How to derive Feffermann-Graham expansion for AdS Vaidya geometries?
Introduction
The Feffermann-Graham expansion for an asymptotically AdS spacetime [0] looks like Poincare AdS but with the flat space replaced by a more general metric i.e.
$$ds^2=\frac{1}{z^2}(g_{\mu \...

AdS compactification of Minkowski space
I am trying to understand the paper "Anti De Sitter Space And Holography" by E. Witten (cf. https://arxiv.org/abs/hep-th/9802150).
One of the first point it makes is that "Minkowski ...

Reparameterization invariance in gravity
It's often said that gravity/general relativity has 'reparameterization invariance.' In particular, this comes up when people talk about the duality between the Sachdev-Ye-Kitaev (SYK) model and ...

Boundary in AdS / CFT correspondence
In AdS / CFT correspondence, the boundary with 2D conformal field theory refers to the observer who is at the center of the 3D AdS space. What will happen when the coordinates of the observer change? ...

Metric form of $AdS_5 \times S^5$
I want to know the metric form of $AdS_5 \times S^5$.
I know there are two forms (maybe more?) Poincare patch and global patch.
And what is the difference between these two patches?
Can you state the ...

Question about $\rm AdS$ conformal boundary in Poincare coordinates
I've worked $\rm AdS$ using global coordinates and the ideas of a conformal boundary is plausible. Radial $\rho$ coordinate can be compactified and we can study its conformal boundary at $\frac{\pi}{2}...
