The bicovariant differential calculus on the three-dimensional   Kappa-Poincar'e group
  The bicovariant differential calculus on the three-dimensional Kappa-Poincar'e group and the corresponding Lie-algebra structure are described. The equivalence of this Lie-algebra structure and the three-dimensional $\kappa$-Poincar\'e algebra is proved.
