摘要：

We discuss string theory alpha(1) corrections in the dual description of the expanding boost invariant Nu = 4 supersymmetric Yang-Mills plasma at strong coupling. We compute finite 't Hooft coupling corrections to the shear viscosity and find that it disagrees with the equilibrium correlation function computations. We comment on the possible source of the discrepancy. (C) 2008 Elsevier B.V. All rights reserved.
