Unitarity in the 't Hooft limit
Consider a quantum gauge theory with a holographic dual at infinite $N$ and 't Hooft coupling, in which the gauge theory is described by classical (super)gravity.
If I initialize the system in a pure ...

What are Bubbling Geometries?
I know that Wilson loops in certain higher rank representations are dual to Bubbling Geometries. Also, certain local operators are dual to this kind of solutions. But (independently from holography), ...

Derivatives as "dynamical variables of the theory"?
This question will probably sounds very broad.
So, I work with classical general relativity, a bit of field theory and semiclassical gravity. I have a friend, though, that works with things like ...

MAGOO 2-Point Correlation function derivation
I am studying the famous MAGOO review and I am trying to understand section 3.3 where we calculate the correlation functions from the AdS side. In subsection 3.3.1 the authors go through the 2-point ...

Spin-2 operators from metric fluctuations in the AdS/CFT
This is a computational question. I am pretty sure that there is a simple explanation, and something obvious that I am missing but I cannot figure it out.
I want to add that this is not meant to be a &...

Confusion about Generating Functionals in AdS/CFT
I have a question regarding an equation in the book "Gauge/Gravity Duality" by Martin Ammon and Johanna Erdmenger which however can also be found in other AdS/CFT books or lecture notes.
The ...

Is Supergravity just Super String Theory without open strings?
I'm trying to understand the elements of the AdS-CFT correspondence. The definition I have in mind is a correspondence between:
(A) a Super String Theory of $D_p$-branes and closed strings in a $10$d ...

What is a protected states in Supersymmetry, Superstring theory context
I know that they are the states that have protected scaling dimension when couplings are changed. But there are some states that are protected only in free orbifold theory, this is something I don't ...

Relationship between scaling dimension and mass in AdS/CFT
I've been reading Horatiu Nastase's notes on AdS/CFT, but I was confused about a certain relationship he claimed. If we compactify supergravity on $AdS_5\times S^5$, we may expand the fields in Kaluza-...

Holographic duals of (super)gravity sigma models
Consider a (super)gravity theory on asymptotically AdS spacetime $N$ with fixed conformal boundary $\partial N$ coupled to scalars $\phi_i$ taking values in a manifold $M$, possibly in addition to ...

What is the origin of the five-form field in bubbling Ads geometries?
I have been reading the paper: Bubbling Ads space and the 1/2 BPS geometries[hep-th/0409174]. In the paper they look at 1/2 BPS states in the field theory which are dual to D3 branes IIB supegravity. ...

Global symmetries in type IIB string theory vs type IIB supergravity
In the AdS/CFT correspondence I know that the mapping of global symmetries involves also the S duality that in the field theory side is $SL(2,Z)$. In Type IIB supegravity this duality is $SL(2,R)$. I ...

From String Frame to Einstein Frame for 10D supergravity
This question is related to but not answered in the post String frame and Einstein frame for a Dp-brane, so it should be treated as a separate question.
Beginning with the gravity action

Breitenlohner-Freedman (BF) stability condition
I am looking for a simple way to derive the Breitenlohner-Freedman (BF) bound. Actually I can't understand why we have stability above the BF bound and instability below the BF bound, while both have ...

Superconformal approach to supergravity
In the book (Supergravity - Daniel Z.Freedman & Antoine Van Proeyen - Cambridge), there is (Chapters 16-17) a presentation of pure supergravity or supergravity with matter, from a superconformal ...
