Braid group action and twisted quantum affine algebras [PDF]
Naihuan Jing, Honglian ZhangThe 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.View original: http://arxiv.org/abs/1301.3550
