Braid group action and twisted quantum affine algebras    [PDF]

Naihuan Jing, Honglian Zhang
The Drinfled realization of quantum affine algebras has been tremendously useful since its discovery. Combining techniques of Beck and Damiani with our previous approach, we give a complete and conceptual proof of the Drinfeld realization for the twisted quantum affine algebras using Lusztig's twisted braid group action.
