comment Connection beween infinite gauge symmetries and UV finiteness
1.) One of the problems with the SUSY argument is, that Vasiliev theory is not supersymmetric and so it does not apply. 2.) I'm not sure if I understand you but let me rephrase your second statement to see if i maybe do: It is usually hard to find the right counterterm (of the many possible ones) and symmetries help (since they restict the possiblities of possible counterterms) to find the right one which finall helps to renormalize the theory.

comment Connection beween infinite gauge symmetries and UV finiteness
Thank you for the answer. So there seems to be a connection between more gauge symmetries and better quantum properties. Could you maybe explain (or be more explicit) about the systematics of that claim. There might be some (general) arguments for that claim?

comment Regarding the possibility of Closed Timelike Curves
@Danu Yes. So AdS in physics is usually a universal cover of the real AdS

comment Regarding the possibility of Closed Timelike Curves
@Danu When you connect two sides of a piece of paper (which is "real" Ads) you are able to go around it in circles (timelike closed curves). Since we do not want that we flatten the paper out again (i.e., we disconnect the two sides).

@Danu What physicists usually mean by AdS is the universal cover of AdS.

comment Does anyone take the Wightman axioms seriously?
@user33923 Maybe you should update your question accordingly. I think to say if they are taken seriously is a little bit harsh. Maybe inspirehep.net/record/1094230 is an interesting read.

Is beeing part of an US$1,000,000 problem serious enough ;)? en.wikipedia.org/wiki/Yang%E2%80%93Mills_existence_and_mass_gap

comment What is the CFT dual to pure gravity on AdS$_3$?
Be aware that i could easily be not be up to date. So take that with a grain of salt. Hopefully a more knowledgeable user will add something.

comment How to get general relativity from linear gravity theory?
I'm not sure if i understood you correct, but i think the end of Section 4.1. + the references in Quantum Gravity: a Progress Report by S. Carlip seem relevant.

comment Why isn't the Bekenstein-Hawking Entropy considered the quantum gravitational unification?
@juanrga When you go to arxiv.org/abs/1110.5322 and look at "Cite as:" the link it to the Abstract and not to the paper.
