摘要：

We compare quantum corrections to semiclassical spinning strings in AdS(5) X S-5 to one-loop anomalous dimensions in N = 4 supersymmetric gauge theory. The latter are computed using the reduced (Landau-Lifshitz) sigma model and with the help of the Bethe ansatz. The results of all three approaches are in remarkable agreement with each other. As a byproduct we establish the relationship between linear instabilities in the Landau-Lifshitz model and analyticity properties of the Bethe ansatz. (c) 2005 Elsevier B.V. All rights reserved.
