> Title: On some new constructions in quantum vertex algebra theory
> Abstract
>
>
> One important problem in the vertex algebra theory is to associate
> certain vertex algebra-like objects, the quantum vertex algebras, to
> various classes of quantum groups, such as quantum affine algebras or
> double Yangians. In this talk, after giving a brief introduction to the
> 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.
