摘要：

The dilatation operator measures scaling dimensions of local operator in a conformal field theory. Algebraic methods of constructing the dilatation operator in four-dimensional N = 4 gauge theory are reviewed. These led to the discovery of novel integrable spin chain models in the planar limit. Making use of Bethe ansatze a superficial. discrepancy in the AdS/CFT correspondence was found, we discuss this issue and give a possible resolution. (C) 2004 Academie des sciences.
