Maths HEP Lunchtime Seminars: Yangians and strings in AdS_3
31 January 2014 13:00 in CM221
We will review recent progress in understanding the scattering theory for strings propagating on AdS_3 backgrounds. The role of Yangians will be discussed, and the new features displayed by this case when compared to the AdS_5 background will be highlighted. Finally, the issues of massless modes will be discussed.
