Higher Sugawara operators for the quantum affine algebras of type A

14 May 2015 Frappat Luc Jing Naihuan Molev Alexander Ragoucy Eric

We give explicit formulas for the elements of the center of the completed quantum affine algebra in type $A$ at the critical level which are associated with the fundamental representations. We calculate the images of these elements under a Harish-Chandra-type homomorphism... (read more)
