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

Abstract

We use the isomorphisms between the $R$-matrix and Drinfeld presentations of the quantum affine algebras in types $B$, $C$ and $D$ produced in our previous work to describe finite-dimensional irreducible representations in the $R$-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 $R$-matrix and Drinfeld presentations of the Yangians.

includes a review of arXiv:1705.08155, arXiv:1903.00204 and arXiv:1911.03496
