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