Maths HEP Lunchtime Seminars: Quantum group symmetry on the half-line
11 January 2002 13:00 in CM221
"When integrable systems are placed on the half-line by imposing integrable boundary conditions, their quantum group symmetry algebra is broken to a subalgebra. I will show how to construct this symmetry algebra and how to use it to obtain the reflection matrices without having to solve the reflection equation. I will concentrate on the sine-Gordon model but also mention our results for the principal chiral models and affine Toda field theories."
