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.

Evaluation-type deformed modules over the quantum affine vertex algebras of type $A$
The authors link suitably generalized deformed phi-coordinated modules of the quantum affine vertex algebra V^c(gl_N) to representations of U_h(gl_N) and O_h(Mat_N), showing that its center at critical level c=-N prod...
