Query: The bicovariant differential calculus on the kappa-Poincare group and on
  the kappa-Minkowski space   The bicovariant differential calculus on the four-dimensional kappa-Poincare
group and the corresponding Lie-algebra like structure are described. The
deifferential calculus on the n-dimensional kappa-Minkowski space covariant
under the action of the kappa-Poincare group is constructed.
