Drinfeld Realization of Affine Quantum Algebras: The Relations
Abstract
In this paper the structure of the Drinfeld realization q of affine quantum algebras (both untwisted and twisted) is described in details, and its defining relations are studied and simplified. As an application, a homomorphism from this realization to the Drinfeld and Jimbo presentation qDJ is provided, and proved to be surjective.
