Invariants of the extended twisted -Yangian
Lucia Bagnoli, Slaven KožiÄ, Jian Zhang
We investigate the extended twisted -Yangian , a certain algebra which admits both the orthogonal and the symplectic -Yangian as its quotients. We…

On two families of quantum vertex algebras of FRT-type
Lucia Bagnoli, Marijana Butorac, Slaven KožiÄ
We consider two new families of quantum vertex algebras which are associated with the type trigonometric -matrix and elliptic -matrix of the eight-vertex model. We show t…
