Abstract: (SIGMA)
Following the approach of Ding and Frenkel [Comm. Math. Phys. 156 (1993), 277-300] for type AA, we showed in our previous work [J. Math. Phys. 61 (2020), 031701, 41 pages] that the Gauss decomposition of the generator matrix in the RR-matrix presentation of the quantum affine algebra yields the Drinfeld generators in all classical types. Complete details for type CC were given therein, while the present paper deals with types BB and DD. The arguments for all classical types are quite similar so we mostly concentrate on necessary additional details specific to the underlying orthogonal Lie algebras.
