Maths HEP Lunchtime Seminars: Hidden Dualities and Symmetries in String Sigma Models

Presented by Martin Wolf, DAMTP Cambridge

29 January 2010 13:00 in CM221

In this talk, I will review some recent developments in our
understanding of hidden dualities and symmetries in string sigma
models. I will first discuss certain 2d dualities and their
implications on the so-called dual superconformal symmetry. I will
explain that this symmetry has its origin in the integrability of the
superstring sigma model in AdS5 x S5. I will then move on and explain
that the superstring sigma model arises from a dimensional reduction
of some 8d self-dual Yang-Mills theory which in turn has a twistorial
interpretation. This thus offers another possibility of using twistor
theory to explore the (geometric) properties of the hidden symmetry
structures of the dual gauge theory.
