What are the implications of supersymmetry generators satisfying a majorana condition?
hoping to resolve some confusion I have about this paper (https://arxiv.org/abs/hep-th/9904017) regarding the holographic dual of a flow from ${\cal N}=4$ SYM to an ${\cal N}=1$ SUSY theory.
Broadly ...

Definition of “quasi-locality” in Wilsonian RG scheme
I’m studying about the holographic RG with this paper.
In that paper they say Wilsonian action expects quasi locality, but I’m not sure what “quasi-locality" exactly means.
If quasi-locality ...

Confusion regarding the Susskind-Uglum conjecture
I have a very basic confusion regarding entropies in holography. In AdS/CFT, the Susskind-Uglum conjecture states that the generalized entropy of a bulk region, given by
$$S_{\text{gen}}(A) = \frac{\...

Divergence of gauge kinetic coupling at the AdS boundary
This is the Einstein-Maxwell-Dilaton Gravity action:
\begin{eqnarray*}
S_{EM} = -\frac{1}{16 \pi G_5} \int \mathrm{d^5}x \sqrt{-g} \ [R - \frac{f(\phi)}{4}F_{MN}F^{MN} -\frac{1}{2}D_{M}\phi D^{M}\...

Motivation of Holographic Exact Renormalisation Equation
I've recently been studying exact renormalisation alongside holographic renormalisation, and came across the following paper on the arXiv: https://arxiv.org/abs/hep-th/0001193.
I'm trying to ...

How AdS/CFT solves the non-renormalizability of gravity?
According to AdS/CFT, all gravity calculation in AdS can be mapped to CFT calculations on the boundary. Then what are the loop divergences in AdS gravity be mapped to the CFT side? Or put it ...

Black holes in AdS/CFT
In Swingle's work Entanglement Renormalization and Holography, he mentioned that a black hole in AdS bulk corresponds to a finite temperature boundary state. With the MERA picture of the entanglement ...

Appropriate gauge-invariant counterterms for Maxwell field in $AdS_5$
I am starting with the bulk Maxwell field in $AdS_5$, and want to calculate the on-shell action. My metric is
$$ds^2 = \dfrac{dz^2 - dt^2 + \vec{dx^2}}{z^2}$$
from which I calculate the on-shell ...

Why holographic renormalization?
Why is there a need to perform holographic renormalization for the normal $AdS_5\times S^5$/CFT$_4$ correspondence if the brane theory is conformal? Since the flow along the AdS direction $r$ is ...

What is the definition of a "UV-complete" theory?
I would like to know (1) what exactly is a UV-complete theory and (2) what is a confirmatory test of that?
Is asymptotic freedom enough to conclude that a theory is UV-complete?
Does it become ...

Derivation of Eq. 7.12 in the review paper of Kraus
I'm reading "Lectures on black holes and the $AdS_3/CFT_2$ correspondence" by Kraus.
http://arxiv.org/abs/hep-th/0609074
I don't know how one can obtain Eq.7.12. My stupid question is how to obtain ...

Holographic Renormalization in non-AdS/non-CFT
In AdS/CFT, the story of renormalization has an elegant gravity dual. Regularizing the theory is done by putting a cutoff near the conformal boundary of AdS space, and renormalization is done by ...
