Jordanian twists on deformed carrier subspaces
Petr P. Kulish, Vladimir D. Lyakhovsky
The nontrivial subspaces with primitive coproducts are found in the deformed universal enveloping algebras. They can form carrier spaces for additional Jordanian twists. The latter…

Twist deformations for Yangians
Vladimir D. Lyakhovsky
It is demonstrated how chains of twists for classical Lie algebras induce the new twist deformations (the deformed Yangians) that quantize the generalized rational solutions of the…
