... In this talk we establish the following relation between the categories of representations of the two algebras: we show that the category of modules over the small quantum group is naturally equivalent to the category of modules over the big quantum group, which have a so called Hecke eigen-property with respect to representations lifted by means of the quantum Frobenius map from the category of representations of the Langlands dual Lie algebra. ...
