Abstract:
In this paper, we explicitly prove that an integrable system solved by the quantum inverse scattering method can be described by a pure algebraic object (universal R-matrix) and a proper algebraic representation. For the example of the quantum Volterra model, we construct the L-operator and the fundamental R-matrix from the universal R-matrix for the quantum affine Uq(ˆsl2) algebra and q-oscillator representation for it. In this way, there is an equivalence between the integrable system with the symmetry algebra A and the representation of this algebra.
