Factorizable S Matrices and Symmetry Operators
Zhan-Ning Hu
Abstract
In this paper, the factorizable S matrices with toroidal rapidity values are constructed explicitly and the symmetry operators of which tensor product commutes with S are found. These operators have a structure which is similar to the ordinary Hopf algebra. As a limit of the elliptic case sl q (2) quantum algebra with q N = 1 can be obtained from the symmetry operators.
