摘要：

We review and compare the integrable structures in N = 4 gauge theory and string theory on AdS(5) x S-5. Recently, Bethe ansatze for gauge theory/weak coupling and string theory/strong coupling were proposed to describe scaling dimensions in the su(2) subsector. Here we investigate the Bethe equations for quantum string theory, naively extrapolated to weak coupling. Excitingly, we find a spin chain Hamiltonian similar, but not equal, to the gauge theory dilatation operator. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
