Orthogonal and symplectic Yangians - linear and quadratic evaluations
arXiv:1712.06849 · doi:10.1016/j.nuclphysb.2018.05.022
Abstract
Orthogonal or symplectic Yangians are defined by the Yang-Baxter relation involving the fundamental matrix with or symmetry. Simple operators with linear or quadratic dependence on the spectral parameter exist under restrictive conditions. These conditions are investigated in general form.
