Abstract

We consider the Etingof-Kazhdan quantum vertex algebra Vc(R)\mathcal{V}^c(R) associated with the trigonometric and elliptic RR-matrix of type A.A. We establish a connection between (restricted) modules for the hh-Yangian Yh(glN)\textrm{Y}_h(\mathfrak{gl}_N) and the elliptic quantum algebra Ah,p(gl^2)\mathcal{A}_{h,p}(\widehat{\mathfrak{gl}}_2) of level zero, and deformed (twisted) ϕ\phi-coordinated Vc(R)\mathcal{V}^c(R)-modules. As its application, in the trigonometric case, we construct new families of central elements of Vc(R)\mathcal{V}^c(R) at the critical level c=N,c=-N, which we then use to derive commutative families in the hh-Yangian Yh(glN).\textrm{Y}_h(\mathfrak{gl}_N).
