Quantum vertex algebra associated to quantum toroidal $\mathfrak{gl}_N$ (2405.09386v1)

Abstract: In this paper, we associate the quantum toroidal algebra $\mathcal{E}N$ of type $\mathfrak{gl}_N$ with quantum vertex algebra through equivariant $\phi$-coordinated quasi modules. More precisely, for every $\ell\in \mathbb{C}$, by deforming the universal affine vertex algebra of $\mathfrak{sl}\infty$, we construct an $\hbar$-adic quantum $\Z$-vertex algebra $V_{\widehat{\mathfrak{sl}}{\infty},\hbar}(\ell,0)$. Then we prove that the category of restricted $\mathcal{E}_N$-modules of level $\ell$ is canonically isomorphic to that of equivariant $\phi$-coordinated quasi $V{\widehat{\mathfrak{sl}}_{\infty},\hbar}(\ell,0)$-modules.
