As an occupation, I'm a mathematical physicist, studying string theory and quantum field theory.

I've developed as a hobby a few Cocoa (Touch) apps. The largest one so far is spires.app, which manages articles and metadata downloaded from the arXiv eprint server, the inspire database, and the journal websites.

I'm also interested in many other things, which is why I ask questions in various StackExchange sites ...

comment Paper listing known Seiberg-dual pairs of N=1 gauge theories
Ah, I see. Then I'll award him the bounty, but I don't accept his answer!

comment Paper listing known Seiberg-dual pairs of N=1 gauge theories
I agree. I think Urs deserves many points anyway through his contribution to tp.se at large, so I "accept" his answer :)

comment Paper listing known Seiberg-dual pairs of N=1 gauge theories
@Joe I knew that the list doesn't exist in the literature, that's why I asked here :p I learned that I should've asked this question after the tp.se community grew up more.

comment Paper listing known Seiberg-dual pairs of N=1 gauge theories
@Urs: That paper by Mukhopadhyay and Ray only talks about SU groups, so your characterization of it as about "non-exceptional" sounds a bit off the point to me. Also, on your ncat page, you say Seiberg duality is formalized as derived equivalences of quivers, but mathematical quivers are again only for U or SU groups... I don't understand why most of the mathematicians only care about U(N) quivers. They can easily analyze SO or Sp quivers, can't they???

Nobody has given me the definitive list as the answer. So, the bounty will be lost, too bad!

comment Paper listing known Seiberg-dual pairs of N=1 gauge theories
@Urs There are also Pouliot's class of Seiberg dualities, where a chiral theory is mapped to a non-chiral one: arXiv.org/abs/hep-th/9507018 etc. Can I convert my question to a community wiki, and make the answer itself as the list?

comment Paper listing known Seiberg-dual pairs of N=1 gauge theories
Thanks, but neither of them is complete, e.g. they don't contain duals with exceptional gauge groups ...

comment Scaling solutions in context of Denef - Moore
Also, the discussions of scaling solutions in the paper by Denef-Moore did not satisfy everyone (including you). This led to a few related papers, e.g. arxiv.org/abs/0807.4556 . So, when you have a very specific question in a paper, you shouldn't just ask it here... You need to think about it yourself, and then write a paper about it.

comment Scaling solutions in context of Denef - Moore
Yes indeed. But you need to understand that Prof. Moore is almost the most rigorous person as far as string theorists are concerned. You need to learn to relax and read what the authors meant behind what is in fact written. (Un)fortunately, string theory is not math.

Thanks, but I was not asking for reviews. I'm looking for a comprehensive list of dual pairs.

comment Is there a theorem that says that QFT reduces to QM in a suitable limit? A theorem similar to Ehrenfest's theorem?
Physically speaking, you shouldn't care about those niceties. Nobody knows if the real word coordinates is really described by real numbers. They may just be rational numbers, or maybe of the form (very, very small number) x integer. Real numbers might be our approximation.

comment Is there a theorem that says that QFT reduces to QM in a suitable limit? A theorem similar to Ehrenfest's theorem?
No, being East Asian, I just loosely quoted a word of Confucius. (The original parable was that he advised a person to eat more, and advised another person to eat less. A disciple who was seeing this was confused, and asked the master why he gave opposite advice. Confucious said that the first person was somewhat fat and the second person was somewhat thin, and the advise should be made according to the person.) To be a bit more specific, I guess your answer (about infrared divergence, etc.) was too high level for the original question, leading to the down votes. I didn't down vote you.

@VladimirKalitvianski Being correct and being pedagogical are not always the same, I guess.

Ah, thank you. Could you edit your answer accordingly (sorry for my mistake in my original question)? I'll accept yours immediately.

comment Other processes than formal power series expansions in quantum field theory calculations
Also note that this asymptotic series proves to be extremely precise, e.g. the theoretical result for $g-2$ calculated in this series agrees with the experiment to 10 significant digits. See en.wikipedia.org/wiki/Anomalous_magnetic_dipole_moment
