摘要：

We use the real-time finite-temperature AdS/CFT correspondence to compute the effect of general R-2 corrections to the gravitational action in AdS space on the shear viscosity of the dual gauge theory. The R-2 terms in AdS(5) are determined by the central charges of the CFT. We present an example of a four-dimensional gauge theory in which the conjectured lower bound of 1/4 pi on the viscosity-to-entropy ratio is violated for finite N.
