Resumen:
By taking into account the full order(alpha´^3) type IIB string theory corrections to the supergravity action, we compute the leading finite ´t Hooft coupling order(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
