The full correlator in the limit is given by a non-trivial function of two variables: One variable is the charge of the BPS operators divided by the square root of the number Nc of colors; the other variable is the octagon that contains all the ’t Hooft coupling and spacetime dependence. At each genus g in the large Nc expansion, this function is a polynomial of degree 2g + 2 in the octagon. We find several dual matrix model representations of the correlators in the large-charge limit. Amusingly, the number of colors in these matrix models is formally taken to zero in the relevant limit.eng1/N ExpansionAdS-CFT CorrespondenceIntegrable Field TheoriesSupersymmetric Gauge TheoryArtigo10.1007/JHEP08(2019)162Acesso aberto2-s2.0-85071653967
