Abstract
We consider the Etingof-Kazhdan quantum vertex algebra $\mathcal{V}^c(\mathfrak{gl}_N)$ associated with the trigonometric $R$-matrix of type $A$. By combining Li's theory of $\phi$-coordinated modules and the ideas from our previous paper, we introduce the notion of deformed $\phi$-coordinated quantum vertex algebra module. We show that the orthogonal twisted $h$-Yangians and restricted modules for the generalized orthogonal twisted $h$-Yangians can be equipped with the structure of (truncated) deformed $\phi$-coordinated $\mathcal{V}^c(\mathfrak{gl}_N)$-module and demonstrate its applications.| File | Dimensione | Formato | |
