Abstract
Using the duality conjecture between N=6 supersymmetric U(N)_ktimes U(N)_{-k} Chern-Simons theory and M-theory on AdS_4 times S^7/Z_{k}, we calculate the corrections to the shear viscosity of the field theory at temperature T. At strong t Hooft coupling and at small k level, we have considered one-loop correction to the M-theory effective action. At large k level, we have considered the alpha correction to the type IIA effective action. In both cases the correction to the ratio of shear viscosity to the entropy density is positive
