Center of the quantum affine vertex algebra in type A (1603.00237v2)
Published 1 Mar 2016 in math.QA, math-ph, math.MP, and math.RT
Abstract: We consider the quantum vertex algebra associated with the double Yangian in type A as defined by Etingof and Kazhdan. We show that its center is a commutative associative algebra and construct algebraically independent families of topological generators of the center at the critical level.
