> main concepts of quantum vertex algebra theory, I will discuss the 
> aforementioned problem in the setting of the Etingof-Kazhdan quantum 
> affine vertex algebra associated with the trigonometric R-matrix of type 
> A. The main focus will be on its connection with the representation 
> theory of the quantum affine algebra of type A, the explicit description 
> of its center at the critical level and some further applications to the 
> construction of certain commutative subalgebras. The talk is in part 
> based on the joint works with Lucia Bagnoli and Alexander Molev.
