Abstract

If an algebraA is quantum commutative with respect to the action of a quasitriangular Hopf algebraH, then the monoidal structure on the categoryH of modules overH induces a rnonoidal structure on the categoryA#H of modules over the associated smash productA # H. The condition under which the braiding structure ofH induces a braiding structure onA#H is further investigated. Dually, the notion of quantum cocommutativity is introduced, and similar result in this dual situation is obtained.
