Orthogonal and symplectic Yangians - linear and quadratic evaluations

24 May 2018  ·  Karakhanyan D., Kirschner R. ·

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. read more
