PBW and duality theorems for quantum groups and quantum current algebrasBenjamin EnriquezB. EnriquezIRMA and Université Louis Pasteur, 7 rue René Descartes, 67084 Strasbourg, France enriquez@math.u-strasbg.fr Abstract: We give proofs of the PBW and duality theorems for the quantum Kac-Moody algebras and quantum current algebras, relying on Lie bialgebra duality. We also show that the classical limit of the quantum current algebras associated with an untwisted affine Cartan matrix is the enveloping algebra of a quotient of the corresponding toroidal algebra; this quotient is trivial in all cases except the $A_1^{(1)}$ case.
