Interrelations between Quantum Groups and Reflection Equation (Braided) Algebras
Abstract
We show that the differential complex B over the braided matrix algebra BMq(N) represents a covariant comodule with respect to the coaction of the Hopf algebra A which is a differential extension of GLq(N). On the other hand, the algebra A is a covariant braided comodule with respect to the coaction of the braided Hopf algebra B. Geometrical aspects of these results are discussed.
