Second-order evaluations of orthogonal and symplectic Yangians
Orthogonal or symplectic Yangians are defined by the Yang–Baxter RLL relation involving the fundamental R-matrix with the corresponding so ( n ) or sp (2 m ) symmetry. We investigate the second-order solution conditions, where the expansion of L ( u ) in u −1 is truncated at the second power, and we...
