Abstract
We compute the correlation functions of R-charge currents
and components of the stress-energy tensor in the strongly coupled
large-N finite-temperature 
= 4 supersymmetric Yang-Mills theory,
following a recently formulated minkowskian AdS/CFT prescription. We
observe that in the long-distance, low-frequency limit, such
correlators have the form dictated by hydrodynamics. We deduce from
the calculations the R-charge diffusion constant and the shear
viscosity. The value for the latter is in agreement with an earlier
calculation based on the Kubo formula and absorption by black branes.
