Twisted $\phi$-coordinated modules for vertex algebras and Zhu's correspondence theorem
Abstract
Let be a vertex algebra and be an automorphism of of order . For any , we construct an -bimodule , where denotes the associative algebra constructed by the authors in \cite{Shun1}. We introduce the notion of -graded -twisted -coordinated -modules and prove that there exists a bijection between the simple -modules and the irreducible -graded -twisted -coordinated -modules, where . We construct the universal enveloping algebra , showing that is subquotient of . When is vertex operator algebra, we show that each is isomorphic to the -bimodule constructed by Dong and Jiang~\cite{DJ2}. Also we prove that there exists a bijection between the irreducible admissible -twisted -modules and the irreducible -graded -twisted -coordinated -modules.
