摘要
We investigate the shear viscosity eta and the entropy density s of strongly coupled N = 4 super Yang-Mills (SYM) plasma in late time of hydrodynamic evolution with AdS/CFT duality and Bjorken scaling. With the metric g(mu nu) obtained through holographic renormalization, we compute eta/s in 2+1 dimension with radial flow. Our result is consistent with the Kovtun-Son-Starinets bound if next-to-leading terms in proper time are included in the equation of motion for metric perturbations.
