摘要：

By taking into account the full O(alpha'3) type IIB string theory corrections to the supergravity action, we compute the leading finite 't Hooft coupling O(lambda-(3/2)) corrections to the conductivity of strongly-coupled SU(N) N = 4 supersymmetric Yang-Mills plasma in the large N limit. We find that the conductivity is enhanced by the corrections, in agreement with the trend expected from previous perturbative weak-coupling computations.
