Take the tour ×  This in the context of the AdS/CFT
correspondence. I am reading this review on AdS/CFT Aharony et.
al. (The MAGOO review) The abstract can be found here  Equation
(2.50) of the above paper lists the $R$-symmetry groups of
extended supersymmetries in $AdS_{p+2}$. He uses the following
notation for the group:  $AdS_5: SU(2,2 | {\cal N}/2),~{\cal
N}=2,4,6,8$  Can anyone explain this notation to me?
share|improve this question Beisert has a nice chapter on this
arxiv.org/abs/1012.4004 which is part of the huge AdS/CFT-
integrability review. –  Vibert Jun 14 at 21:36 Thanks. Let me
read through them and get back to you. –  Prahar Jun 15 at 0:08
