Remarks on $\phi$-coordinated modules for quantum vertex algebras

12 Aug 2016 · Li Haisheng ·

This paper is about $\phi$-coordinated modules for weak quantum vertex algebras. Among the main results, several canonical connections among $\phi$-coordinated modules for different $\phi$ are established. For vertex operator algebras, a reinterpretation of Frenkel-Huang-Lepowsky's theorem on contragredient module is given in terms of $\phi$-coordinated modules.
