Abstract
We formulate a prescription for computing Minkowski-space
correlators from AdS/CFT correspondence. This prescription is shown
to give the correct retarded propagators at zero temperature in four
dimensions, as well as at finite temperature in the two-dimensional
conformal field theory dual to the BTZ black hole. Using the
prescription, we calculate the Chern-Simons diffusion constant of the
finite-temperature 
= 4 supersymmetric Yang-Mills theory in the
strong coupling limit. We explain why the quasinormal frequencies of
the asymptotically AdS background correspond to the poles of the
retarded Green's function of the boundary conformal field theory.
