Representations of Quantum Affine Algebras in their $R$-Matrix Realization

Representation Theory 2020-12-29 v2 Quantum Algebra

Abstract

We use the isomorphisms between the RR-matrix and Drinfeld presentations of the quantum affine algebras in types BB, CC and DD produced in our previous work to describe finite-dimensional irreducible representations in the RR-matrix realization. We also review the isomorphisms for the Yangians of these types and use Gauss decomposition to establish an equivalence of the descriptions of the representations in the RR-matrix and Drinfeld presentations of the Yangians.
