Loop realizations of quantum affine algebras

Cautis, Sabin; Licata, Anthony


We give a simplified description of quantum affine algebras in their loop presentation. This description is related to Drinfeld's new realization via halves of vertex operators. We also define an idempotent version of the quantum affine algebra which is suitable for categorification.
