We show that little string theory on S^5 can be obtained as double-scalinglimits of the maximally supersymmetric Yang-Mills theories on RxS^2 andRxS^3/Z_k. By matching the gauge theory parameters with those in the gravityduals found by Lin and Maldacena, we determine the limits in the gauge theoriesthat correspond to decoupling of NS5-brane degrees of freedom. We find that forthe theory on RxS^2, the 't Hooft coupling must be scaled like ln^3(N), and onRxS^3/Z_k, like ln^2(N). Accordingly, taking these limits in these fieldtheories gives Lagrangian definitions of little string theory on S^5.Comment: 16 pages, 5 figures. Minor change
