Description
We review the computation of anomalous dimensions in planar N=4 super Yang-Mills theory from an integrable system, i.e. AdS_5/CFT_4 ''integrability''. We then introduce the hexagon operator originally designed by Basso, Komatsu, and Vieira for three-point functions. It is argued that four- and higher-point functions can be studied using hexagon tessellations. A ''gluing prescription'' for the elementary tiles leads to
sum-integrals akin to the MB representation. We comment on the status quo,
open problems, and research directions.
