Drinfeld Realization of Quantum Twisted Affine Algebras via Braid Group

الملخص EN

The Drinfeld realization of quantum affine algebras has been tremendously useful since its discovery.

Combining techniques of Beck and Nakajima with our previous approach, we give a complete and conceptual proof of the Drinfeld realization for the twisted quantum affine algebras using Lusztig’s braid group action.
