The nonlinear K3 surface of a high-energy QCD model

We study the nonlinear K3 surface of the high-energy QCD model with four types of algebras: the $AdS_4$ and the $AdS_5$ algebras with the $SU(4)$ symmetries. We find that the nonlinear K3 surface can be constructed using the properties of the four-brane K3 surface of the high-energy theory in three dimensions.
