Abstract: | A bicovariant calculus of differential operators on a quantum group is constructed in a natural way, using invariant maps from Fun

g, given by elements of the pure braid group. These operators—the reflection matrixYL

SL
– being a special case—generate algebras that linearly close under adjoint actions, i.e. they form generalized Lie algebras. We establish the connection between the Hopf algebra formulation of the calculus and a formulation in compact matrix form which is quite powerful for actual computations and as applications we find the quantum determinant and an orthogonality relation forY inSO
