Orthogonal and symplectic Yangians: Linear and quadratic evaluations

Orthogonal or symplectic Yangians are defined by the Yang–Baxter RLL relation involving the fundamental R matrix with so(n) or sp(2m) symmetry. Simple L operators with linear or quadratic dependence on the spectral parameter exist under restrictive conditions. These conditions are investigated in ge...

Zusammenfassung:Orthogonal or symplectic Yangians are defined by the Yang–Baxter RLL relation involving the fundamental R matrix with so(n) or sp(2m) symmetry. Simple L operators with linear or quadratic dependence on the spectral parameter exist under restrictive conditions. These conditions are investigated in general form.
