The spectrum of IIB supergravity on AdS5 × S5/\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ {{\mathbb{Z}}_3} $\end{document} and a 1/N2 test of AdS/CFT

We present the complete Kaluza-Klein spectrum resulting from the compactification of IIB supergravity on S5/\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ {{\mathbb{Z}}_3} $\end{document}. Knowledge of this spectrum allows us to perform a holographic computation of the difference of central charges c − a of the dual SU(N)3 quiver gauge theory. We find the numerical value c − a = 3/16, in exact agreement with the field theory result.
