Integrability in gauge theory and string theory III
Nick Dorey
(Cambridge/Imperial Maths Institute)
Abstract:
In these lectures, I will introduce the concept of integrability and study its realisation in the context of gauge theory and string theory. In particular, I plan to review recent progress in computing the spectrum of operator dimensions in N=4 supersymmetric Yang-Mills theory and the dual problem of determining the spectrum of string theory on AdS5 x S5.

Dilatation operator for N=4 SYM vs giant gravitons and open strings
Guillermo Silva
(Universidad Nacional de La Plata)
Abstract:
We will discuss the one-loop anomalous dimensions of Super Yang-Mills operators dual to open strings ending on AdS giant gravitons (AGG) and describe the spin chain description of gauge theory operators. A semi-classical analysis of the Hamiltonian describing the anomalous dimensions of AGG operators will allow us to give a geometrical (stringy) interpretation for the gauge theory parameters. This same analysis will also show evidence for the existence of continuous bands in the Hamiltonian spectrum.
