Twist deformations for Yangians
Vladimir D. Lyakhovsky
Abstract
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 classical Yang-Baxter equation. For the case of Y(g) with g=so(2N+1) the explicit expression for the corresponding R-matrix is given in the defining representation.
