Triangular quasi-Hopf algebra structures on certain non-semisimple quantum groups
C. A. S. Young, R. Zegers
One way to obtain Quantized Universal Enveloping Algebras (QUEAs) of non-semisimple Lie algebras is by contracting QUEAs of semisimple Lie algebras. We prove that every contracted…

On kappa-deformation and triangular quasibialgebra structure
C. A. S. Young, R. Zegers
We show that, up to terms of order 1/kappa^5, the kappa-deformed Poincare algebra can be endowed with a triangular quasibialgebra structure. The universal R matrix and coassociator…
