Integrability in gauge theory and string theory II
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.

Electromagnetic duality and the Langlands programme
David Olive
(University of Swansea)
Abstract:
A recent paper by Kapustin and Witten synthesises ideas from
pure mathematics and quantum field theory that have been developing independently for more than thirty years. Thus the Langlands programme, itself a unification scheme in mathematics, relates to electromagnetic duality and
the topological twisting of supersymmetry. An attempt will be made to explain these ideas.
